The NFL will no longer allow the Las Vegas Raiders to use a holder on kickoffs in order to improve hang time.

Josh McDaniels explained that the Raiders got the idea to have the ball placed on the top of the tee, rather than inside the tee, because it puts the ball slightly higher off the ground.

McDaniels said the Raiders first got clarification from the NFL that a holder is allowed to hold the ball on the top of the tee, and the league confirmed that it's legal.

However, after the league's officiating department discussed the matter with the competition committee, the determination has been made that footballs can only be placed in the tee and not on the tee.
