Well, it's official. Michigan will even be more depleted in the defensive backfield in 2010 as Donovan Warren has let Coach Rod know that he is heading to the NFL for sure.

“He’s officially gone,” Warren’s father Alvin told GoBlueWolverine moments ago. “He told Coach Rod this morning.”

Warren had 63 tackles and four picks (with 1 TD) in 2009. He is also rated the No. 2 junior CB in the draft by Mel Kiper.

DW has also hired a famous agent: "I'm confident in my ability," he said. "I'm ready for the next chapter in my life." (on his NFL status) "It was pretty broad, but they said I could go in the first or second round," said Warren, adding he has signed with agent Drew Rosenhaus.

This loss to the Michigan defense means that freshman Justin Turner is most likely a starter (competing with JT Floyd) at one corner with Troy Woolfolk at the other. True freshman Cullen Christian, Courtney Avery, and Adrian Witty will also get a shot at playing time.

This news may also have an affect on the recruitment of California safety Sean Parker who has Michigan in his top three with CAL and USC. Having Sean on the team would allow Woolfolk to stay at corner (he moved from the safety position late in the year).

There is also a chance that former 5 star recruit Boubacar Cissoko gets re-instated if he gets his academics in order.
