Troy Woolfolk played well enough in his first game at cornerback last week that Michigan football coach Rich Rodriguez expects him to stay at that position the rest of the year.

"I think he could go back at safety at anytime, but right now we’re solid with him at corner," Rodriguez said Wednesday.

Woolfolk, who moved from safety to corner last off-season, started opposite Donovan Warren at right cornerback and wasn't challenged much against the Hawkeyes.

Boubacar Cissoko, who started the first four games at right corner, is suspended indefinitely. J.T. Floyd, who started against Michigan State, is Michigan's No. 3 corner.

Woolfolk said he learned he was changing positions last week when he got a text message from secondary coach Tony Gibson.

"I was in the middle of class and I got a text from my coach talking about he wants to have a talk with me," Woolfolk said. "I initially thought I had done something wrong because I’m not one of the greatest kids. So I come to the meeting and I’m scared and stuff, and the first thing he says is I’m still going to be playing. So whatever he says after that, I don’t care what happened."

More practice notes • Kelvin Grady has seen his playing time at slot receiver diminish over the last two weeks in favor of starter Martavious Odoms.

"I don’t want to say he hit a rookie wall, but he is a rookie," Rodriguez said. "In the last couple games we felt more comfortable in tight situations having the experienced guy, which was Tay, in there, as opposed to Kelvin. And I’ve challenged Kelvin and said, 'Listen, I know you’re a freshman and all that and hitting that midway point, but we still have confidence in you and we know you can do it, and we want your role to continue to increase just like it was early in the year.'"

• Delaware State quarterback Anthony Glaud missed most of last week's game with a head injury. Rodriguez said he's preparing for Glaud to start, but was prepared if Nick Elko got the call instead.

"I think irregardless of the quarterback they’re going to run the same system," Rodriguez said. "The only time you worry as a coach is if they run two different systems or styles, and I think they’ll run the same."

• Rodriguez on how he envisions splitting carries between Brandon Minor and Carlos Brown once both are healthy: “I didn’t realize Brandon had 22 (against Iowa) until after the game. But he can handle that, and I think Carlos can handle that. They're talented enough, depending on the situation, that with those two in particular, if they both had between 15 and 20 that would be kind of perfect."
