FAYETTEVILLE — Arkansas quarterback Tyler Wilson’s availability for Saturday’s game against top-ranked Alabama remained uncertain Thursday, although coach John L. Smith said the senior did not participate in the Razorbacks’ final practice of the week.

Smith, who said earlier this week he was holding out hope Wilson could return from a hit to the head that knocked him out of the Louisiana-Monroe game. He did not reveal much information after Arkansas wrapped up their closed practice Thursday.

“I’ve got no answers,” Smith said. “Nothing for you today.”

Smith, defensive coordinator Paul Haynes and several players confirmed Wilson participated in Wednesday’s practice and said he looked good throwing. Smith was asked how Wilson was able to practice Wednesday, but couldn’t Thursday.

Smith’s answer: “He was busy.”

Smith later said Wilson did not suffer a setback.

Arkansas continues to prepare backups Brandon Allen and Brandon Mitchell to play against the Crimson Tide. Neither has started at quarterback in their Arkansas careers, although Allen played the entire second half of the ULM loss. He completed 6 of 20 passes for 85 yards with a touchdown and an interception.

Smith said both quarterbacks have handled the responsibility of preparing for a start against an Alabama defense that is ranked among the nation’s best. Smith did not say which quarterback would get the start if Wilson can’t play Saturday.

“I think they’re both right there right now,” Smith said. “Tied.”

Smith said the latest Wilson could be cleared to play against the Crimson Tide would be Friday morning.

He said at that point “a decision has to be made” for Saturday's game.

"Like I said, (Wednesday) he had a great day. He threw it around. He felt good," Smith said. "It was very positive. We're just going to have to wait and we'll get word this evening."
