Midway through the third quarter Saturday night, Arizona sophomore safety Jared Tevis frantically waved his arms above his head, encouraging the UA fans to get as loud as possible.
It was vintage Tevis. The former Canyon del Oro High School standout will take any chance to fire up his teammates and get the crowd rocking.
There was one major difference in Saturday's 38-35 loss to Oregon State, and it wasn't a good one.
Tevis, who entered the game as the UA's second-leading tackler, was waving his arms on the Arizona sideline with his left leg in a walking boot and his shoulder pads back in the Wildcats' locker room.
He suffered a left ankle injury late in the first quarter after defending a pass in the end zone. After lying on the field for several minutes, he limped off to the Wildcats sideline with the help of two trainers.
Tevis came back for one series, but clearly wasn't at full strength. The Beavers took advantage of his bum ankle and completed a 38-yard pass, which eventually led to a Storm Woods rushing touchdown.
He didn't return after the long completion and watched the second half nervously from the sideline.
It's a big blow to the Wildcats.
Three days before the game, Wildcats coach Rich Rodriguez was clear on how valuable Tevis has been this season.
"Jared probably could have been our player of the week in every week so far," Rodriguez said Wednesday.
The UA secondary missed Tevis. Oregon State quarterback Sean Mannion threw for 278 yards and a touchdown in the first half.
Mannion had completions of 25, 38, 51 and 57 yards in the first half alone.
Tevis' injury wasn't the only one Saturday night for the Wildcats.
Starting senior center Kyle Quinn suffered a right leg injury in the second half and was replaced by fellow senior Addison Bachman.
Bachman, named a captain for the game during the week, actually recorded a catch in the fourth quarter after a Matt Scott pass was deflected by an Oregon State defender.
It wasn't clear if Quinn's injury was to his leg or ankle, but the Brentwood, Calif., native was in pain.
Quinn's injury was the second to a UA starting offensive lineman. Right guard Trace Biskin, listed as questionable before the game, didn't play because of a toe injury. Shane Zink started and rotated in the game with true freshman Cayman Bundage.
Arizona also was undermanned on the defensive line. Reggie Gilbert, a starting lineman, missed the game with an ankle injury. Like Biskin, Gilbert was listed as questionable, but didn't play.
Dan Pettinato, a sophomore, started for Gilbert.
Also missing the game was senior wide receiver Terrence Miller. Redshirt freshman David Richards started for him.
UA linebacker Marquis Flowers was also dinged up in the fourth quarter. He was replaced by freshman C.J. Dozier.
The 100 club
Sophomore Ka'Deem Carey rushed for more than 100 yards for the third time this season. He finished with 117 yards on 15 carries. Carey also went over the century mark in the team's first two games of the season against Toledo and Oklahoma State.
The running back from CDO has gained at least 71 yards in each game this year.
Coming into the season, his career high for yards in a game was 67, which came on nine carries against UCLA.
Carey also added two touchdowns Saturday, giving him seven for the season. He had six rushing scores as a freshman.
• The two teams combined for more than 1,000 yards of offense (1,158), the second time that's happened in 2012. Arizona and Oklahoma State combined for 1,137 yards in Week 2.
• Arizona cornerback Jonathan McKnight's streak of consecutive games with an interception ended at three. He picked off a pass against Oklahoma State, South Carolina State and Oregon.
