Wilson suffered a concussion in the first half of Arkansas' 34-31 overtime loss to Louisiana-Monroe and missed all of the Razorbacks' 52-0 home loss to top-ranked Alabama.
Wilson has been tested daily and got clearance on Thursday per Smith. Smith said the players and team got a lift with that news. Smith said the practices had proceeded as if Wilson would play. Offensive coordinator Paul Petrino said on Tuesday that Wilson got 50 percent of the snaps with the first unit in that practice.
"It's been a good week of practice," Smith said. "We got good news this morning. Tyler is cleared to go and we are very excited."
Smith said the news was a lift to the team.
"It was," Smith said. "They are fired up. Gosh, a whole week of practice is not for naught. Tyler brings energy, a positive attitude and a vocal presence. They need that. The positive spirals."
Smith said Wilson may have missed the last six quarters and some practice, but it wasn't evident with the way he practiced.
"He's practiced well," Smith said. "Tyler is Tyler. I've had quarterbacks miss before, but nothing like this. It's different now with the what you are seeing because the medical advancements are so great. We are much more conscious of (concussions)."
Smith said there could be some tweaks to the defensive alignment. Senior Tenarius Wright, a solid defensive end for the last three seasons, might return at least some of the time to that position. He's started at middle linebacker the past three weeks after moving there ahead of spring drills.
The head coach said Wright's "stinger" symptoms from an injury early in camp would be easier to handle with a different style of contact at defensive end as compared to the bigger collisions at linebacker.
"We had planned to use him some at end in some scenarios," Smith said. "Getting him back there might lessen the stingers and keep him healthy."
Alonzo Highsmith will move from weakside linebacker to middle linebacker if Wright is at end. Smith said other linebackers now in the mix include Terrell Williams, Otha Peters and A. J. Turner.
"Those other guys have to step up," Smith said. "I'm mainly talking about Turner and Williams."
Smith was asked if Wilson's return changed how the Hogs would handle the blitz. The Scarlet Knights blitz from all angles, much as ULM did in the game that Wilson last played.
"Certainly, we are not planning on him getting hit," Smith said. "He has to make the checks in protection (against blitzes) and that's part of our system. It's not just a concern this week, but every week."
Smith said Brandon Mitchell has practiced some at quarterback this week, but mostly at wide receiver. That means Brandon Allen is listed as the backup for Rutgers.
"The other two are both prepared to go," Smith said, noting the option with Mitchell is still a possibility.
Smith was asked if there is more respect for Wilson after what he's endured in the last two weeks?
"I think I have (gained more respect)," Smith said. "But I think we as coaches have had it all along. He's an inspirational leader for this team. I took (from Wilson's statement after Saturday's game) that we all have to look in the mirror."
Is it a must win for the Razorbacks?
"They are all must," Smith said. "This fits right in there with two weeks ago and last week."
