MADISON, Wis. -- Wisconsin head coach Paul Chryst announced Monday that junior center Dan Voltz (knee) will miss the rest of the season.

Voltz returned from an elbow injury for last Saturday's 24-13 win over Illinois, but went down in the second half and did not return. Voltz will not only miss the remainder of the regular season, but Wisconsin's bowl game as well.

The Badgers will turn to freshman Michael Deiter at center, who moves over from right guard.

"He's done a lot of really good things for us," Chryst said of Deiter. "He doesn't flinch. He rolls with it."

Voltz, a three-year starter, has held down the center position for 27 games, including 21 of the last 22.

Wisconsin is now down its third starting offensive lineman, as Chryst also announced that sophomore Hayden Biegel and senior Ray Ball likely would not likely return this season either.

With Voltz out, freshman Micah Kapoi moves to left guard as the Badgers will finish the season with three freshman on its offensive lineman -- assuming this is it on the injury front, which isn't a safe assumption based on the 2015 season.

"The expectation is that those guys will get better," said Chryst. "We'll get them ready. That's part of coaching, to give them a chance to have success. We'll never put in a guy that's not ready, who could go back in his growth or development."

To add to Wisconsin's injury woes, junior wide receiver Rob Wheelwright could miss the rest of the season as well. Wheelwright left Saturday's win at Illinois with a leg injury and Chryst was hopeful he could potentially return for the bowl game.

"I feel bad for Rob," said Chryst. "He was playing really good football. Yet, it will give some other guys an opportunity to step up."

Wheelwright has 28 receptions for 369 yards and four touchdowns in 2015.
