Johnny Manziel made the start Saturday for No. 16 Texas A&M against Vanderbilt. The Heisman Trophy winner started despite an apparent shoulder injury. Manziel participated fully in warm-ups with the team and took the first team snaps in 7-on-7 drills. Manziel was limited in practice throughout the week but has thrown as much he has been able to, according to sources. Manziel, who suffered the injury to his throwing shoulder in Texas A&M's 45-41 loss to Auburn last week, was called "hopeful" to play by coach Kevin Sumlin earlier this week. Manziel injured his right shoulder when he was tackled by two Auburn defenders at the end of an 8-yard run with 14:36 remaining in the fourth quarter against Auburn. Manziel grabbed his right shoulder before getting up then fell to the turf as he was walking back to the sideline and was attended to by the Aggies' training staff. When testing his throwing arm by trying to throw a football on the sideline, Manziel could be seen wincing from the pain. He received treatment from the A&M training staff and returned to the game with 9:06 to go.
