COLUMBUS, Ohio -- Cramps and an injured knee have kept quarterback Braxton Miller from playing a complete game so far this season, but it's too early to tell whether his latest health scare will keep him out of the lineup for No. 4 Ohio State.
Miller has a strained MCL in his left knee and is uncertain for Saturday's game at California, coach Urban Meyer said Monday.
"Braxton Miller is a day-to-day decision," Meyer said during his Monday news conference. "He's feeling much better, but he's just a little stiff."
Miller, a junior, is expected to practice Tuesday.
"Braxton just got done throwing a little bit, and he's going to practice some," Meyer said Tuesday. "We'll know more (Wednesday) if he'll be available for the Cal game. ... Can he plant? Can he move? I'll know more after practice."
Miller was limited to just one possession in a 42-7 win for the Buckeyes over San Diego State on Saturday, leaving early in the first quarter after he went down awkwardly between two defenders while scrambling to convert a fourth down. Miller was helped off the field and didn't return to the game, although he was fitted for a brace and potentially could have gone back in if needed, Meyer said.
Senior Kenny Guiton played the rest of the game while Miller, who finished fifth in Heisman Trophy voting last season, watched from the sideline in a scarlet baseball cap.
The Buckeyes (2-0) survived just fine with Guiton under center, as the backup kept the spread offense humming with 83 rushing yards, 152 passing yards and three touchdowns.
Guiton was also effective in relief in the season-opening win over Buffalo, coming off the bench to toss a touchdown pass while Miller was dealing with cramps.
Although Guiton has played an instrumental role in Ohio State's 14-game winning streak, Miller is widely viewed as the most critical component if the Buckeyes are to compete for a national championship.
"If he's healthy enough to play -- and to play like Braxton Miller -- he'll play," Meyer said. "He'll certainly go. We're not saving anything."
