ANN ARBOR, Mich. -- Michigan quarterback Wilton Speight remains "day-to-day" with a shoulder injury, according to head coach Jim Harbaugh, heading into a rivalry game against Ohio State with playoff implications this coming week.
Speight did not play for the Wolverines in a 20-10 win over Indiana on Saturday afternoon. He started the first 10 games of the season but injured his non-throwing shoulder in a loss to Iowa on Nov. 12. In the week leading up to Saturday's game, Harbaugh said Speight's status was up in the air, and that message didn't change during the coach's postgame comments.
"We'll see," Harbaugh said when asked if Speight will practice at the start of this week. "It's day-to-day."
Redshirt junior John O'Korn replaced Speight in the starting lineup Saturday. He completed seven of his 16 pass attempts for 59 yards and ran for 19 net yards. He scrambled for 30 yards on a third-down play that breathed some life into a stagnant Wolverines offense in the third quarter.
Harbaugh said he was pleased with O'Korn, especially given the conditions on a windy, snowy evening in Ann Arbor.
"It was tough conditions to operate, especially in the passing game," Harbaugh said. "He did extremely well. Ball security was fantastic all day. He managed the team and did what he needed to do."
Michigan's offense gained only 110 yards in the first half and failed to convert a third-down attempt until the third quarter. O'Korn said the offense didn't get off to a good start, but he didn't think that was due to any rust he had. O'Korn's last start came as a sophomore at Houston in October 2014. He transferred to Michigan last spring.
After the game last Sunday afternoon, O'Korn said he knew that he would be the starter for this weekend's game. He said he planned to spend the next week preparing as if he'll be on the field against the No. 2-ranked Buckeyes in Columbus next Saturday.
"If (Speight)'s ready to go, that's coach's decision," O'Korn said. "I'll support 100 percent whatever the coaches decide. I know we'll both be ready to go."
Speight dressed in pads for Saturday's game and threw briefly during warm-ups.
Both Michigan and Ohio State are likely to remain among the top four teams in the country heading into their season finale against each other. A Michigan win would clinch a trip to the Big Ten title game for the Wolverines.
