Tim Clark's emergency dental surgery last week accomplished enough that he won't have to finish the procedure until next week, when the Oregon State football team has a bye.
Clark's need to have all his wisdom teeth removed became known after the season began. The plan was to wait until the bye week to get all of them done at one time.
However, the pain escalated to the point that the cornerback couldn't get much sleep at night.
"It has been hurting me for a while now," Clark said. "I tried to hold out until the bye week, but what happened with one of my wisdom teeth was it impacted on the left side touching my teeth. One of them was cracked and a high risk for infection so I had to take it out immediately."
The recovery kept him out of practice much of last week so he didn't start, but played significantly at Arizona State.
He's back practicing with the first-team this week.
"I tired to block it out," Clark said of the open wounds in his mouth during the game. "If you don't, you'll play slower and hesitant. I didn't feel anything in the game, but there was some concern of knocking something loose."
Clark expects the week off during the bye will be enough recovery time for the major surgery so he'll be back to practice the following week when preparations for the Oct. 24 game at Southern California begin.
Safeties Cameron Collins and Lance Mitchell ran with the first string in practice this week. Clark and Brandon Hardin mixed with the first team at corner.
Defensive tackle Brennan Olander worked with the first team after taking the first practice of the week off to rest his knee.
"We are pretty well settled in what we are going to do, like we did in the last game," coach Mike Riley said of the defense. "It's status quo this week."
Wide receiver Casey Kjos (back) eased back into practice after missing three games. Jordan Bishop, Aaron Nichols and Kjos shared the work at slot.
Backup safety Anthony Watkins will not dress for the game, Riley said.
Watkins bruised his shoulder during Wednesday's practice. The injury isn't expected to be a long-term issue.
However, his injury does hurt the special teams, where Watkins leads the team in special teams tackles with five.
Stanford's 4-1 start is the best since the 2001 team got off to a 5-1 start. That team was the last one to go to a bowl game.
The 3-0 Pacific-10 Conference start is the best since the 1999 team won the first five and went to the Rose Bowl.
Stanford's three-game winning streak is the longest since 2005.
The Beavers defeated Stanford 30-23 on Oct. 10, 1998, at Stanford Stadium. That was Riley's first Pac-10 win. He has 34 now. OSU faces the Cardinal on Saturday, which is also Oct. 10.
