ANN ARBOR, Mich. -- Baltimore Ravens defensive coordinator Greg Mattison is leaving to fill the same role on Brady Hoke's new staff at Michigan.
Mattison was also the defensive coordinator for the Wolverines during the 1995 and 1996 seasons.
"Greg loves Michigan, loves recruiting and is excited about coming back to Ann Arbor and the University of Michigan," Hoke said in a statement. "Greg is one of the top defensive coordinators in football, and his defensive units have always prided themselves on stopping the run. He will be a great asset to our program and an excellent addition to our staff."
Hoke has also hired seven other members of his staff a week after he was hired as Michigan's 19th football coach.
Offensive coordinator Al Borges, special teams coordinator Dan Ferrigno, offensive line coach Darrell Funk, wide receivers coach Jeff Hecklinski, linebackers coach Mark Smith and strength and conditioning coach Aaron Wellman are coming with Hoke from his previous staff at San Diego State.
Longtime Michigan running backs coach Fred Jackson has been rehired to the same position.
Mattison was a co-defensive coordinator at Florida for three seasons from 2005-07. He then joined the Ravens as their linebackers coach in 2008 before serving as Baltimore's defensive coordinator the last two seasons.
Mattison also spent eight seasons (1997-2004) on the staff at Notre Dame.
"He has loved Michigan since working there earlier in his career," Ravens coach John Harbaugh said in a statement. "Greg is one of the good people you are fortunate to meet in your life. We are disappointed that he will not be coaching our defense, but we know that he is following a true love by returning to the Wolverines."
