Michigan CB Woolfolk carted off with ankle injury
Michigan cornerback Troy Woolfolk sprained his left ankle in the second quarter and didn't return in a 34-10 win over Western Michigan on Saturday.
''If we needed him, he was going to go back in,'' coach Brady Hoke said.
Woolfolk was hurt covering a kickoff in the second quarter Saturday against Western Michigan. He missed all of last season with an injured right ankle.
Courtney Avery replaced Woolfolk for the Wolverines.
