STANFORD — Cardinal center Tim Mattran, who has overcome his share of injuries during a six-year career on The Farm, might have one more comeback up his sleeve.

Mattran was in uniform at practice Wednesday and walked without a limp, four days after a high-ankle sprain against Notre Dame left him on crutches.

"They gave me some new drugs yesterday, and I'm responding to them really well," said

Mattran, who was given anti-inflammatory medication. "I woke up this morning, and it felt great. It was a big step last night to this morning. We're hoping we'll get another one, and I can go out and do this thing."

Mattran has started all 11 games this season but hasn't finished the past two. He suffered an injury to his right ankle Nov. 10 against Washington State. Saturday, he injured his left ankle.

Mattran was on crutches Tuesday and heard that he probably wouldn't be able to play against Cal. But he walked into the football office Wednesday with his crutches over his shoulder.

"They kept me out of the team stuff (Wednesday)," Mattran said. "I don't know what our plan is (today). I think it's kind of a wait-and-see and make a decision from there."

Mattran's motivation for playing is simple: "To be here six years and not start a Big Game would be kind of tough to look back on," he said.

If Mattran cannot play, redshirt freshman Bert McBride would start.

STARTING QB TBA: Another day, still no starting quarterback for the Cardinal.

However, coach Jim Harbaugh did say after practice Wednesday that both Tavita Pritchard and T.C. Ostrander will get onto the field against the Bears.

"I'll tell you what I told them: They're both going to play; they're both talented guys; and they (both) bring things to the table that could potentially help us move the ball," Harbaugh said. "Practice is reinforcing that this week."

The repetitions have been even, Harbaugh said.

EXTRA POINT: Tailback Anthony Kimble (shoulder) is still questionable for Saturday's game. If he doesn't play, the Cardinal would go with the trio of Jeremy Stewart, Tyrone McGraw and Corey Gatewood.
