Michigan defensive coordinator Greg Mattison recently slipped on some ice, injuring his quadriceps.
Offensive coordinator Al Borges told the Detroit News, "I showed up right after the crime. I saw him laying there on the ground with his wife (Ann), and I said, 'What's going on?' He said, 'Oh, I slipped on the ice.' And he was hurting. We had to get an ambulance. We couldn't move him. We tried to move him, and he was howling."
According to the Detroit News, the injury required a surgery for Mattison, who is will be back in the office on Monday.
Just yesterday, ESPN analyst Urban Meyer called Mattison, “the best recruiter in college football.” While on set with ESPNU, Meyer stated, “He’s not only one of the best defensive coordinators in America, but also the best recruiter in college football.”
Mattison served on Meyer’s staff at Florida from 2005-2007 before joining the Baltimore Ravens staff. This is Mattison’s second stint at Michigan. From 1992-1994, he coached the Wolverines defensive line. In 1995-1996, he served as the defensive coordinator.
Michigan opens the 2011 season with four consecutive non-conference games against Western Michigan, Notre Dame (night game), Eastern Michigan, and San Diego State.
Here's a pretty good video interview with Mattison.
