Beginning in 2011, live-ball penalties will be assessed from the spot of the foul and eliminate the score. Examples include players finishing touchdown runs by high-stepping into the end zone or pointing the ball toward an opponent.
Celebration penalties following a score will continue to be assessed on conversion attempts or the ensuing kickoff.
"I think one of the reasons it's been looked at is that when a penalty occurs on the field, it's normally taken from the spot," Teaff said. "This was the only occurrence that it wasn't taken from the spot, so they wanted to change that."
Taunting has caused an annual debate among college football players, coaches and fans, and last season's big controversy stemmed from Georgia receiver A.J. Green receiving a 15-year personal foul penalty after he caught a go-ahead touchdown pass late in a game against LSU.
The yardage from the penalty was assessed on the kickoff and helped LSU get into position to drive for the winning score. Southeastern Conference officials said later that there was no video evidence to support the flag on Green.
Lynch called it an area that needed to be cleaned up and said he supported taking away scores.
"Just run it into the end zone, how hard is that?" he said after a spring practice. "It is a team game and that's what makes it such a great game."
A third change bans the use of eye black containing symbols or messages, a trend that grew in popularity because of the use by Heisman Trophy winners Reggie Bush and Tim Tebow.
The committee also approved a rule that will require all coaches boxes to have television monitors beginning in the fall of 2011.
In soccer, the rules committee approved changes for new soccer field dimensions, requiring them to 70 to 75 yards wide and 115 to 120 yards long. All fields in current use have been approved and will not be subjected to change.
