The Seattle Seahawks are saying goodbye to running back Christine Michael again.

In a surprise move, the Seahawks placed Michael on waivers Tuesday, says NFL Network Insider's Ian Rapaport.

Michael was the Seahawks' primary running back for the season, leading Seattle with 117 carries, 469 rushing yards and six rushing touchdowns. With Thomas Rawls out with a leg injury and the Seahawks switching through other running backs, Michael was a consistent player. Rawls is expected to return to the field against the Eagles on Sunday.

Rapaport says the decision was not based on any off-the-field drama and was strictly a "football decision."

ESPN's Adam Schefter reports 31 teams have shot to claim him, so we'll see on Wednesday what's next for him in the NFL.

The team drafted Michael in the second round of the 2013 NFL draft but traded him to the Dallas Cowboys in 2015. Michael appeared in five games with Dallas, was released, and subsequently joined the Washington Redskins practice squad. Seattle re-signed him last December, and then again in March, to help fill the void that Marshawn Lynch left.
