Clipping (gridiron Football)
In gridiron football, clipping is the act of a "throwing the body across the back of the leg of an eligible receiver or charging or falling into the back of an opponent below the waist after approaching him from behind, provided the opponent is not a runner."This is the NFL's definitionRule 3, Section 5/ref> It is also clipping to roll up on the legs of an opponent after a block. It is usually illegal, but in the National Football League it is legal to clip above the knee in close-line play. The Canadian Football League has similar definitions, prohibitions and exceptions, including that "application of penalty is determined by the initial contact". In most leagues, the penalty is 15 yards, and if committed by the defense, an automatic first down. It is prohibited because it has the potential to cause injury. Injuries that can be caused by a clipping violation include those to the collateral and cruciate ligaments and the meniscus. Clipping was first banned in 1916 in the NCAA, and ...

Penalty (gridiron Football)
In gridiron football, a penalty is a sanction assessed against a team for a violation of the rules, called a foul. Officials initially signal penalties by tossing a bright yellow colored penalty flag onto the field toward or at the spot of a foul. Many penalties result in moving the football toward the offending team's end zone, usually either 5, 10, or 15 yards, depending on the penalty. Most penalties against the defensive team also result in the offense receiving an automatic first down, while a few penalties against the offensive team cause them to automatically lose a down. In some cases, depending on the spot of the foul, the ball is moved half the distance to the goal line (American football), goal line rather than the usual number of yards, or the defense scores an automatic Safety (gridiron football score), safety. Rationale Because football is a high-contact sport requiring a balance between offense and defense, many rules exist that regulate equality, safety, contac ...

First Down
A down is a period in which a play transpires in gridiron football. The down is a distinguishing characteristic of the game compared to other codes of football, but is synonymous with a "tackle" in rugby league. The team in possession of the football has a limited number of downs (four in American football, three in Canadian football) to advance ten yards or more towards their opponent's goal line. If they fail to advance that far, possession of the ball is turned over to the other team. In most situations, if a team reaches their final down they will punt to their opponent, which forces their opponent to begin their drive from further down the field; if they are in range, they might instead attempt to score a field goal. Description A down begins with a snap or free kick (such as a kickoff or safety kick), and ends when the ball or the player in possession of it is declared down by an official, a team scores, or the ball or player in possession of it leaves the field of play. ...

Meniscus (anatomy)
A meniscus is a crescent-shaped fibrocartilaginous anatomical structure that, in contrast to an articular disc, only partly divides a joint cavity.Platzer (2004), p 208 In humans they are present in the knee, wrist, acromioclavicular, sternoclavicular, and temporomandibular joints; in other animals they may be present in other joints. Generally, the term "meniscus" is used to refer to the cartilage of the knee, either to the lateral or medial meniscus. Both are cartilaginous tissues that provide structural integrity to the knee when it undergoes tension and torsion. The menisci are also known as "semi-lunar" cartilages, referring to their half-moon, crescent shape. The term "meniscus" is from the Ancient Greek word (), meaning "crescent". Structure The menisci of the knee are two pads of fibrocartilaginous tissue which serve to disperse friction in the knee joint between the lower leg (tibia) and the thigh (femur). They are concave on the top and flat on the bottom, articula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
