Herron, Sanzenbacher will miss game with concussions

Posted by ESPN.com's Adam Rittenberg

Ohio State coach Jim Tressel said today that reserve running back Dan "Boom" Herron and reserve wide receiver Dane Sanzenbecher will miss Saturday's game against Purdue (ABC, 3:30 p.m. ET) after sustaining concussions last week at Wisconsin.

Herron was reportedly briefly knocked out after taking a blow from Wisconsin safety Jay Valai. Sanzenbacher also had to be helped off the field after taking a shot from Valai and several other Badgers defenders late in the first half.

"There's all kinds of grades of concussions," Tressel said on the Big Ten coaches' teleconference.
"I don't know the exact diagnosis. We're very conservative in college football when it comes to head injuries. We need to make sure those kids are ready to go."

Herron had most of the carries during the three-game absence of Chris "Beanie" Wells. He ranks third on the team in rushing (262 yards), while Sanzenbacher is fourth in receiving with 10 receptions for 105 yards.

Wells was extremely sore after the Wisconsin game, but Tressel said the junior ran well at Sunday's light workout and should be fine for Purdue. Maurice Wells and Brandon Saine will serve as Wells' primary backups against the Boilermakers.
