Rick McKay, a co-chairman of the competition committee, announced two new rule changes today:
1) Instant replay is permanent, with all stadiums to be updated with high definition equipment.
2) Assistant coaches of playoff teams interviewing for head coaching jobs now have an additional window in the "bye" week before a Super Bowl for a second interview.
McKay noted that the rule allowing a defensive player to wear a headset was rejected.
Also, the 49ers withdrew their proposal to make defensive pass interference a 15-yard penalty unless it was flagrant.
McKay said a handful of other rules will be voted on Wednesday.
Instant replay passed 30-2, with the Bengals and Cardinals voting against it.
