A team cannot buy an excess time out for a penalty. However, a fourth time out is allowed without penalty for an injured player, who must be removed immediately. A fifth time out or more is allowed for an injury and a five-yard penalty is assessed if the clock was running. Additionally, if the clock was running and the score is tied or the team in possession is losing, the ball cannot be put in play for at least 10 seconds on the fourth or more time out. The half or game can end while those 10 seconds are run off on the clock.
