Michigan star wide receiver Nico Collins, who hasn't commented on his status since reportedly signing with an agent in September, is no longer with the team, coach Jim Harbaugh said on Monday.

"Nico is not participating in football right now," Harbaugh said. "I don't have a crystal ball as to if his mind would change on that. I know he's not currently on the team."

No. 18 Michigan opens its season on Saturday at No. 21 Minnesota. Collins had 78 receptions for 1,388 yards and 13 touchdowns over his three-year career, and originally announced his intent to return for his senior season. He had 37 catches for 729 yards and seven scores last year but reportedly decided to opt out this season before the Big Ten announced its plans to return.

It's a significant loss for a team that also had to replace quarterback Shea Patterson, four starting offensive linemen, and receiver Donovan Peoples-Jones, who decided to skip his senior season and enter the NFL draft. Still, Harbaugh said his other receivers have been "really good" this offseason, specifically giving praise to Giles Jackson, A.J. Henning, Cornelius Johnson, Ronnie Bell, Roman Wilson and Mike Sainristil.
