It's magic: Carlos Brown not on Michigan's injury report

Michigan released its official injury report Thursday, and running back Carlos Brown was nowhere to be found.

Brown did not practice Wednesday because of an undisclosed injury and his status for Saturday's game at Iowa is uncertain.

Michigan coach Rich Rodriguez did not address Brown's injury on his radio show Thursday night

Rodriguez has said previously he favors an NFL-style injury report. He even proposed the Big Ten adopt such a measure at the conference meetings last spring.

In the NFL, teams can be fined for excluding injured players from their list.

Center David Molk (foot) and special-teams ace Zac Johnson (shoulder) were the only two players on Michigan's official injury report. Both are out this weekend.

"He's still got a lot of soreness there," Rodriguez said of Molk, who's missed the last two games. "We're going to take it week by week. It's only three weeks in, and the original prognosis was four to six, so hopefully we get a little bit more out of him next week and we'll see where he's at."

Rodriguez also acknowledged that safety Troy Woolfolk has been practicing at cornerback, but did not announce a starter at the right corner position. Woolfolk practiced with the first team on Wednesday. J.T. Floyd replaced Boubacar Cissoko in the starting lineup at the position last week.

"With our situation defensively, we’re trying to find our best combination back there at safety and corner," Woolfolk said. "And Troy gives us a little flexibility because he can play both pretty well."
