Minnesota sophomore center Jon Christenson is out for the remainder of the season after suffering a broken leg in the second quarter of the Gophers' 42-39 win at Indiana.
Christenson underwent surgery Sunday according to Minnesota head coach Jerry Kill.
"You just feel terrible," Kill said to the St. Paul Pioneer Press. "The game of football is a great game. But it's a hard game. He's a beautiful kid and smart. So it's a shame. However, the kid that came in did a tremendous job."
Christenson was replaced by junior Tommy Olson who will also be the starting center this weekend against Penn State.
If the Gophers learned anything from having to start three centers and three quarterbacks last season, it's always to have a backup to your backup. Minnesota's Zac Epping will now be the No. 2 center behind Olson.
"That's why we always preach about depth, quarterbacks and centers," Kill said. "Remember what we went through last year. You can't recruit enough of them."
