Interception-​ ​when​ ​a​ ​defensive​ ​player​ ​interferes​ ​with​ ​a​ ​pass​ ​by​ ​catching​ ​the​ ​ball​ ​instead​ ​of​ ​the
intended​ ​target.​ ​An​ ​interception​ ​is​ ​also​ ​called​ ​a​ ​turn-over,​ ​because​ ​the​ ​ball​ ​is​ ​turned​ ​over​ ​to​ ​the
team​ ​who​ ​intercepts​ ​it.
Intentional grounding- when a quarterback throws the ball away usually to avoid getting sackedthere
is no receiver close to where the ball is thrown. A QB can throw the ball away but there
must be an eligible receiver close to the spot the ball is thrown. This is similar to the in the grasp
penalty​ ​with​ ​the​ ​difference​ ​being​ ​that​ ​the​ ​quarterback​ ​is​ ​not​ ​in​ ​the​ ​grasp​ ​of​ ​a​ ​defender.
Irrefutable evidence- you’ll hear this phrase used in regards to an instant replay challenge. There
must be clear visual evidence from viewing instant replay for a call made on the field to be
overturned. Irrefutable means it is impossible to deny or disprove. There are times when the
instant replay angle is such that the visual evidence is not strong enough for the call to be
overturned.
J
Jerseys- The uniform shirts that players wear. Each player has a number on the front and back of
his jersey and his last name is printed on the back. There are two versions of the jersey- one is
darker in color and one is lighter. The home team has the right to choose whether they will wear
the darker or the lighter jersey. If the home team chooses to wear a dark jersey, the visiting team
must wear their light jersey, and vice-versa. According to NFL rules a player’s jersey must be
tucked​ ​in​ ​at​ ​all​ ​times.
Juke- when a player shakes off a defender by making a quick left-to-right fake. The defender is
not sure which way the offensive player is going to go and so he causes the defender to miss
making​ ​the​ ​tackle.
K
Key Stats- game statistics that are considered to be the most important factors in a game, such as
passing,​ ​running,​ ​turnovers,​ ​etc.
Kickoff- a kickoff happens at the beginning of the game and of the second half, and after every
score, whether a touchdown or field goal. The kicker places the ball on a tee, and the special
teams players line up along side him for the kick. They can only run downfield after the ball is
kicked
