DETROIT — Michigan cornerback Donovan Warren has declared for the NFL draft.

Warren told The Associated Press on Sunday he believes it's the right time to take his game to the next level.

"I'm confident in my ability," he said. "I'm ready for the next chapter in my life."

The junior from Long Beach, Calif., had asked the NFL Draft Advisory Board to project when he would be selected if chose to go pro.

"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.

Warren said he informed coach Rich Rodriguez of his decision earlier on Sunday.

"He was real supportive," Warren said. "He said to let him know if there's anything he can to do help. He also encouraged me to finish my degree."

Warren's four interceptions led the Wolverines in 2009, when no other player on the lackluster defense had more than two.

Michigan will have a hard time replacing Warren and outgoing senior defensive end Brandon Graham.
