COLLEGE STATION -- Texas A&M coach Mike Sherman said Monday that Jerrod Johnson sprained his throwing shoulder in Saturday's loss to Miami, leaving the Aggies' starting quarterback in doubt for the second straight week.

Johnson was hurt in the second quarter of the Hurricanes' 41-23 win at Kyle Field. The 6-foot-5, 229-pound sophomore completed 19 of 32 passes for 275 yards in place of Stephen McGee, who sprained his throwing shoulder against New Mexico on Sept. 6. McGee had started A&M's previous 29 games.

Sherman said Monday that Johnson's injury was less severe than McGee's and he expected both quarterbacks to be ready in time for Saturday's game against Army (0-3).

But Sherman hedged on who would start or when he would make a decision.

"I know I'm being evasive here, which is my choice," Sherman said. "I'm going to take it day-by-day and then see where we end up at the end of the week."

McGee beat out Johnson for the starting job in fall workouts, but he threw two interceptions and was sacked four times in the Aggies' opening 18-14 loss to Arkansas State. McGee was injured in the first quarter against New Mexico and Johnson threw three touchdown passes in relief to lead A&M to a 28-22 win.

Johnson also threw three touchdown passes against Miami, but two came after the Hurricanes had built a 41-10 lead. Johnson also gave away an interception and a fumble that both led to Miami touchdowns.

"I had my ups, I had my downs," Johnson said.

Freshman receiver Jeff Fuller said Johnson has a stronger arm, but McGee has a better handle on Sherman's offense.

"Jerrod made a lot of throws where his size helped him out a lot," said Fuller, who caught five passes for 79 yards. "He broke a few tackles in the backfield and then came up and made the pass. There are a lot of plays like that.

"Steve just knows the offense inside-and-out, probably as good as Coach Sherman knows it," Fuller said. "He'll make all the perfect reads."

Sherman said before the season that he wouldn't use a two-quarterback system, with McGee and Johnson alternating possessions during games. He promised that both McGee and Johnson would see playing time the rest of the season, but he was vague on how that would work.

"I feel good about both guys," Sherman said. "I'm elated that I have both of those quarterbacks on this team. They both have tremendous qualities and attributes that can help us. We could start the game with two quarterbacks. Who knows?"

Sherman said Johnson showed good improvisational skills against Miami, even though he was sacked three times. But Sherman said Johnson needs to work on calling out plays faster and protecting the ball when he scrambles.

"He was fairly creative, at times, when the play broke down, sometimes too creative," Sherman said. "Sometimes, you just wanted him to run for a first down and he's trying to buy himself more time."

McGee did not play against Miami. Sherman said the senior's shoulder would be re-evaluated on Tuesday.

"The decision will be made during the course of the week, how we're functioning and how things are going," Sherman said. "I'm not going to make a presumption right now, without knowing exactly where we are health-wise."

Johnson has been working at receiver since McGee was named the starting quarterback in mid-August. Just like last week, he's preparing for a game not knowing what his role will be.

"At the end of the day, it's not my decision," Johnson said. "It's whatever Coach Sherman thinks is best for the team. Whatever he feels is best, it's the law. I'm happy with whatever decision he makes, because I know it's going to be in the best interests of the team."
