The NCAA banned the horse-collar tackle from college football.
Following the lead of the NFL and acting on a proposal made by its Football Rules Committee, the NCAA will assess a penalty this season when a runner is yanked to the ground from the inside collar of his shoulder pads or jersey.
Rogers Redding , NCAA football secretary-rules editor and coordinator of football officials for the Southeastern Conference, said the horse-collar ban may result in fewer back injuries.
"What we're hearing from trainers and physicians is we're getting some back injuries when the ball carrier is immediately snapped to the ground by being jerked quickly," he said. "If the ball carrier is grabbed by the shoulder or jersey and just ridden to the ground over a couple of yards, that's not going to be a foul."
Other changes announced Wednesday include a clarification of rules on chop blocks, or tackling below the knees, and implementation of a 40-second play clock that will start as soon as the ball is ruled dead.
Previously, a 25-second clock began only on the referee's signal.
GEORGIA: A.J. Green missed considerable preseason practice time with a hip flexor injury, but Georgia wide receivers coach John Eason has seen enough big-play potential from the freshman from Summerville, S.C., to move him into a second-team role at flanker behind Mohamed Massaquoi .
PITTSBURGH: Coach Dave Wannstedt picked Bill Stull as the starting quarterback for the 25th-ranked Panthers this season.
A 6-foot-3, 205-pound junior, Stull took nearly every repetition with the first-team offense during more than two weeks of practice.
N.C. STATE: The Wolfpack's quarterback race is down to two players.
Head coach Tom O'Brien said Wednesday that freshman Mike Glennon will redshirt this season. That leaves returning starter Daniel Evans or redshirt freshman Russell Wilson as O'Brien's options for the opener next week at South Carolina.
LOUISVILLE: Former N.C. State quarterback Justin Burke will transfer to Louisville, Cardinals coach Steve Kragthorpe.
The redshirt sophomore played in three games for the Wolfpack last season, completing two of three passes for 15 yards and an interception.
Burke will sit out the season under NCAA transfer rules.
MARSHALL: Former coach Bob Pruett has denied allegations he was involved in an academic scandal or made athletes lie about a jobs program that drew NCAA sanctions in 2001.
One of the former players who accused Pruett in a sworn affidavit has recanted his statements.
Pruett gave a sworn deposition in May in a federal lawsuit filed by David Ridpath , Marshall's former NCAA compliance officer.
NEW MEXICO: The NCAA put New Mexico's football program on three years of probation Wednesday and cut five scholarships as punishment for academic violations involving two former assistant coaches.
