Of course, that scenario would become more drastic if something happens to starter John Parker Wilson and the backup had to enter the game in a crucial situation. Barnes has taken the snaps at number two quarterback for the past two days, doing "okay" Tuesday and "better" on Wednesday, Alabama Head Coach Mike Shula said.
Decatur walk-on Trent Dean now takes over the scout team, and freshman Will Vandervoort is also running a scout team unit. Barnes took the number two snaps behind Wilson as freshman Greg McElroy, who was running scout team, moves into the regular offense during the Crimson Tide's practice as the number three man.
Running back Roy Upchurch has missed the last two weeks of practice because of an ankle sprain, and he will not play this week, Shula said.
"He'll miss this week and then we will re-evaluate him for next week," Shula said.
Tailback Glen Coffee is still recuperating from a pre-season knee injury. Shula did not officially rule Coffee out for a return this season, but Coffee looks more and more likely for a redshirt with each passing week.
"I'm not sure he's 100 per cent just yet," Shula said. "If we did play him it would be because we want to play him the rest of the season, or otherwise because of injury" to another player.
"He's going to keep getting treatment and we are trying to get him as close to 100 per cent as possible," Shula said.
There still has been no word on the cause of Zeke Knight's dizziness which has kept him out of action the past two weeks.
"I feel for Zeke," Shula said. "We want to make sure we know what it its. There are certain tests that have to be done that take time."
