MOBILE, Ala. (AP) — Notre Dame tight end John Carlson, Louisville quarterback Brian Brohm and Auburn defensive end Quentin Groves have withdrawn from the Senior Bowl due to injury or illness.

Tennessee quarterback Erik Ainge and Auburn tight end Cole Bennett were added to the South roster for Saturday's game, an audition for top senior NFL prospects.

Senior Bowl president Steve Hale said Brohm was unable to recuperate in time from a leg injury sustained the season finale against Rutgers game.

"He worked real hard to get ready for the Senior Bowl, but there was unfortunately not enough time," Hale said Monday. "He was not 100 percent, and being the kind of competitor he is, it's not fair for him to be here and not be 100 percent."

Carlson had a recent stomach ailment that caused him to lose 17 pounds in eight days, Hale said.

"He was working his tail off and all of a sudden 10 days ago, he starts feeling bad," he said.

To fill the vacancy created by Carlson's loss, Missouri tight end Martin Rucker moved from the South team to the North team, and Auburn's Cole Bennett was added to the South team.

Groves won't participate because of a shoulder injury, Hale said.

Ainge, who was 25-of-43 passing for 365 yards and two touchdowns in Tennessee's win over Wisconsin in the Outback Bowl, said he was excited to get invited to Saturday's game showcase for NFL scouts.

"Any time you can see a player throw the ball in person, it's more valuable," Ainge said. "And showing what I can do is why I'm here."

Joining Ainge as South team quarterbacks are Hawaii's Colt Brennan and Kentucky's Andre Woodson. For the North, the quarterbacks are Michigan's Chad Henne, Southern California's John David Booty, and Delaware's Joe Flacco.
