NEW YORK, April 12 (UPI) -- The NFL adopted several rules changes, including making instant replay permanent and making it easier for assistant coaches to interview for other positions.
The actions were agreed to during an NFL owners meeting in March and formally announced Thursday. Instant replay was made permanent.
"We think instant replay has been an accepted part of our game now for a number of years," NFL Competition Committee Co-chairman Rich McKay said. "It's worked quite well."
Other rules involve penalties such as a 5-yard penalty for a player who spikes the ball except after scoring a touchdown; a 15-yard penalty for blocking an eligible receiver below the waist in certain situations; and the offense must be tied or losing before the 10-second clock runoff for excessive timeouts is carried out. The penalty against a defense for excessive crowd noise was eliminated because, the league said, it hasn't been called in several seasons.
Assistant coaches on Super Bowl teams will be allowed to interview a second time for head coaching positions during the off week before the Super Bowl. Also, a team's exclusive rights to an assistant coach's contract ends the second Tuesday after their season has concluded.
