CORVALLIS - The Oregon State football team’s quarterback situation is unclear heading into the week, but whatever comes out for the next game isn’t expected to be a major setback.

Junior starter Lyle Moevao hurt his throwing shoulder Saturday night in Reser Stadium during the team’s 27-25 Pacific-10 Conference win over Arizona State.

His status is day-to-day, coach Mike Riley said Sunday afternoon. Moevao will rest the injury and then see how it feels Tuesday when the team first practices for the next game at UCLA.

“He has got the shoulder deal, either a muscle or an AC joint,” Riley said. “It’s very sore. The best way to say anything is it’s day-to-day. We’ll see where he is (today) and Tuesday in practice.”

Moevao was in good spirits on the sideline of the game, cheering on junior backup Sean Canfield as he led the Beavers to victory. Riley said Moevao remained upbeat Sunday as the team watched video of the game.

Canfield completed 19 of 28 passes for 218 yards and two touchdowns. Balls mostly zipped in accurately, but a few sailed off target.

His only major glitch was a bad read on a pass to the flat that was intercepted for an easy 41-yard return for a touchdown.

“I felt pretty comfortable,” Canfield said. “The end of the first half was a little shaky, but our offense played pretty well as a whole in the second half.

“We came out on fire.”

This was Canfield’s first game under pressure since the 2007 Emerald Bowl.

A midseason shoulder injury led to surgery for the former starter this past

January.

It has been a long, slow recovery process. He missed most of training camp with shoulder pain, and it’s only been about a month since he started practicing with the team, mostly working with the second string.

“I was pleased with what he did,” Riley said. “His knowledge of what we are doing stayed intact.

“He was able to make some plays, and scrambled a little bit.

“The biggest thing I give him credit for is he recovered from that interception for a touchdown. That was a very good sign.”

There was no shoulder pain after the game, Canfield said. Canfield didn’t meet with the medical trainer Sunday, so there were no problems the day after the extended workout.

If Moevao can’t return to his starting role on Saturday or beyond, Canfield will be inserted into the lineup without worry.

“I wanted to have two guys who are capable starters in the Pac-10, and we do feel pretty good about it,” Riley said.

Teammates rallied around Canfield and helped him make the offense go. Moevao is a natural leader, so when he left the game Riley saw a group effort take over.

Physically, Canfield adds the threat of the deep ball and the Beavers quickly went back to that play.

“Sean has been practicing really well, and I knew he was going to be ready,” receiver James Rodgers said. “It felt the same as having Lyle out there. We got trust in both our quarterbacks.”
