interesting (to me) rule thing in the NFL
if there is an injury in the last 2 minutes of the half or the game the team with the injury is charged with a time out
the reason is to prevent the faking of injuries so that a team will benefit by getting more time
but if they have no timeouts when an injury occurs they can be granted, in certain situations, an excess timeout
so faking an injury could still possibly be an advantage play for a team
they may get charged 10 seconds off the clock in this situation if the defense chooses but it would still seem to allow them a potential advantage as they have plenty of time to prepare for another play
the link is the actual official NFL rulebook:
