Chop Block (gridiron Football)
In gridiron football, a chop block is an attempt by an offensive player to cut block (block at the thigh level or lower) a defensive player while the defender is already engaged by another offensive player. The chop block is usually considered illegal and penalized by a loss of 15-yards due to the injury risk it presents to the defender. NFL In the National Football League (NFL), a chop block is an illegal move, penalized by a 15-yard loss. Before the 2016 NFL owners meeting, chop blocks were legal under certain circumstances. It was considered legal on running plays when (i) the blockers were aligned next to each other on the line of scrimmage, (ii) the blockers were lined up anywhere on the line and the flow of the play is towards the block or (iii) the cut blocker was aligned in the backfield and the chop block took place outside the original tight end position. The cut blocker is said to "chop" the defender and usually engages simultaneously with or immediately after the high bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cut Block
In gridiron football, cut blocking is an offensive line technique that consists of an offensive player knocking a defensive player down by hitting his knees. The technique, which was initially instilled by Bobb McKittrick, the offensive line coach of the San Francisco 49ers from 1979 to 1999, is often criticized as being "dirty." Additionally, it is illegal for an offensive player to "cut" a defensive player already engaged with another offensive player. This is considered a " chop block", not a cut block. In the NCAA, cut blocking is allowed as long as the block is away from the original position of the ball. The Fall Experimental Football League and the NFL banned use of the chop block but the cut block remains a legal block in the NFL. Use in the NFL McKittrick was credited as the first to implement cut blocking in his offensive line schemes as the offensive line coach of the 49ers. Les Steckel, the offensive line coach for the Houston Oilers from 1995 to 1999, used cut blocking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Football League
The National Football League (NFL) is a professional American football league that consists of 32 teams, divided equally between the American Football Conference (AFC) and the National Football Conference (NFC). The NFL is one of the major professional sports leagues in the United States and Canada and the highest professional level of American football in the world. Each NFL season begins with a three-week preseason in August, followed by the 18-week regular season which runs from early September to early January, with each team playing 17 games and having one bye week In sport, a bye is the preferential status of a player or team that is automatically advanced to the next round of a tournament, without having to play an opponent in an early round. In knockout (elimination) tournaments they can be granted eit ....

Line Of Scrimmage
In gridiron football, a line of scrimmage is an imaginary transverse line (across the width of the field) beyond which a team cannot cross until the next play has begun. Its location is based on the spot where the ball is placed after the end of the most recent play and following the assessment of any penalty yards. History The line of scrimmage first came into use in 1880. Developed by Walter Camp (who introduced many innovations that are part of the modern game of American football), it replaced a contested scrimmage that had descended from the game's rugby roots. This uncontested line of scrimmage would set into motion many more rules that led to the formation of the modern form of gridiron football (although the Canadian rules were developed independently of the American game, despite their similarities). Dimensions A line of scrimmage is parallel to the goal lines and touches one edge of the ball where it sits on the ground before the snap. In American football, the ...

Tight End
The tight end (TE) is a position in American football, arena football, and Canadian football, on the offense. The tight end is often a hybrid position with the characteristics and roles of both an offensive lineman and a wide receiver. Like offensive linemen, they are usually lined up on the offensive line and are large enough to be effective blockers. On the other hand, unlike offensive linemen, they are eligible receivers adept enough to warrant a defense's attention when running pass patterns. Because of the hybrid nature of the position, the tight end's role in any given offense depends on the tactical preferences and philosophy of the head coach as well as overall team dynamic. In some systems, the tight end will merely act as a sixth offensive lineman, rarely going out for passes. Other systems use the tight end primarily as a receiver, frequently taking advantage of the tight end's size to create mismatches in the defensive secondary. Many coaches will often have one t ...

Canadian Football League
The Canadian Football League (CFL; french: Ligue canadienne de football—LCF) is a professional sports league in Canada. The CFL is the highest level of competition in Canadian football. The league consists of nine teams, each located in a city in Canada. They are divided into two divisions: four teams in the East Division and five teams in the West Division. As of 2022, it features a 21-week regular season in which each team plays 18 games with three bye weeks. This season traditionally runs from mid-June to early November. Following the regular season, six teams compete in the league's three-week playoffs, which culminate in the Grey Cup championship game in late November. The Grey Cup is one of Canada's largest annual sports and television events. The CFL was officially named on January 19, 1958, upon the merger between the Interprovincial Rugby Football Union or "Big Four" (founded in 1907) and the Western Interprovincial Football Union (founded in 1936).

Torn Ligament
A sprain, also known as a torn ligament, is an acute soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movement. Sprains can occur at any joint but most commonly occur in the ankle, knee, or wrist. An equivalent injury to a muscle or tendon is known as a strain. The majority of sprains are mild, causing minor swelling and bruising that can be resolved with conservative treatment, typically summarized as RICE: rest, ice, compression, elevation. However, severe sprains involve complete tears, ruptures, or fractures, often leading to joint instability, severe pain, and decreased functional ability. These sprains require surgical fixation, prolonged immobilization, and physical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medial Collateral Ligament
The medial collateral ligament (MCL), or tibial collateral ligament (TCL), is one of the four major ligaments of the knee. It is on the medial (inner) side of the knee joint in humans and other primates. Its primary function is to resist outward turning forces on the knee. Structure It is a broad, flat, membranous band, situated slightly posterior on the medial side of the knee joint. It is attached proximally to the medial epicondyle of the femur immediately below the adductor tubercle; below to the medial condyle of the tibia and medial surface of its body. It resists forces that would push the knee medially, which would otherwise produce valgus deformity. The fibers of the posterior part of the ligament are short and incline backward as they descend; they are inserted into the tibia above the groove for the semimembranosus muscle. The anterior part of the ligament is a flattened band, about 10 centimeters long, which inclines forward as it descends. It is inserted into ...

Anterior Cruciate Ligament
The anterior cruciate ligament (ACL) is one of a pair of cruciate ligaments (the other being the posterior cruciate ligament) in the human knee. The two ligaments are also called "cruciform" ligaments, as they are arranged in a crossed formation. In the quadruped stifle joint (analogous to the knee), based on its anatomical position, it is also referred to as the cranial cruciate ligament. The term cruciate translates to cross. This name is fitting because the ACL crosses the posterior cruciate ligament to form an “X”. It is composed of strong, fibrous material and assists in controlling excessive motion. This is done by limiting mobility of the joint. The anterior cruciate ligament is one of the four main ligaments of the knee, providing 85% of the restraining force to anterior tibial displacement at 30 and 90° of knee flexion. The ACL is the most injured ligament of the four located in the knee. Structure The ACL originates from deep within the notch of the distal fe ...
