Lyle Moevao is all too aware of Dexter Davis.
Moevao dropped back to throw in the second quarter during last year's game between Oregon State and Arizona State.
Davis, the Sun Devils' defensive end, was bearing in on Moevao's blind side and slammed into him as he released the ball. Moevao was driven into the turf, injuring his shoulder.
He had to have his rotator cuff rebuilt and biceps tendon repaired.
"It was a bad call on my part," Moevao said. "It was a quick throw and the offensive line, they're supposed to block a certain way. I made the wrong read and I paid for it.
"He hit me from my blind side where I was supposed to be looking and I didn't see it coming and unfortunately I landed the wrong way and that set me back a little bit."
While Davis no doubt had no intention to do such severe damage to Moevao's shoulder, he makes it his business to get to the quarterback.
Davis, a 6-foot-2, 255-pound senior right end out of Phoenix, finished the 2008 season with 11 sacks and had 10.5 in 2007. He is the only returning player in the country to have 10 or more sacks in the past two years.
He is fourth on the ASU career sack list with 27.5. Terrell Suggs, now with the Baltimore Ravens, is first with 44.
Moevao compared Davis to former OSU defensive end Victor Butler, who is now playing for the Dallas Cowboys.
"We knew he was really athletic and he was a real good defensive end and he could play the run and the pass very well," Moevao said. "His pass rush is probably his specialty and that's one of the things that we were looking forward to going into the game last year."
Nothing has changed going into Saturday's game at Arizona State.
The Beavers need to protect quarterback Sean Canfield, particularly from Davis. OSU has given up 15 sacks this season.
Canfield expects to see Davis use his experience to try to cause problems for the Beavers.
"I think the biggest thing is experience and any time you've got experience, you've got confidence," Canfield said. "He knows what he's doing and a proven pass rusher. He's proven to get pressure on the quarterback."
