ANN ARBOR, Mich. -- Jim Harbaugh lashed out Tuesday night at Cincinnati coach Luke Fickell, who said Michigan did not support a transfer's attempt to immediately play for the Bearcats.

Harbaugh said he told Fickell months ago he wouldn't lie about what he knew regarding the transfer of James Hudson.

Fickell told The Athletic that Michigan didn't support Hudson's waiver request.

"They can say they didn't undermine it, but they didn't work to help the kid out,'' Fickell said in the story published Tuesday. "All the power is in the hands of the school a player is leaving. If they want to help, they can help them become eligible.''

Harbaugh said that's simply not true.

"Michigan did not block the waiver,'' said Harbaugh, adding it was the NCAA's decision to deny Hudson's request.

The NCAA does not comment on specific waiver cases and rarely do schools, even when an athlete waives protection under federal privacy laws.

Hudson, a seldom-used offensive lineman, transferred to Cincinnati last year. The NCAA denied his waiver request in the spring to be eligible this season. Hudson posted on Twitter that mental health prompted his transfer, but his request was denied because he did not reveal the issues at Michigan.

Hudson, who is from Toledo, Ohio, signed to play at Michigan in 2017 and he redshirted as a freshman and played sparingly as a sophomore.

Harbaugh said Fickell called him in March, trying to coach him what to say about the events leading up to Hudson's transfer.

"I told him, 'I'm not going to lie,''' Harbaugh recalled telling Fickell.

Harbaugh said he talked to Fickell about Hudson switching from offensive to defensive line. As Harbaugh has often said this summer, he believes all college athletes should be able to transfer once without sitting out the following season.

"That's how I personally feel about this issue,'' he said.
