Michael signed with the Seahawks on Wednesday. He was released by the practice squad of the Washington Redskins earlier this week. By Sunday, he could be in uniform for the Seahawks.
Bryce Brown was expected to figure into the mix against the Cleveland Browns this Sunday, but his role could be larger than expected with DuJuan Harris released. Harris had 18 carries for 42 yards after Rawls was injured at Baltimore, but he also had a red zone fumble and averaged just 2.3 yards per carry with a long of six yards.
A second-round pick in 2013, Michael never carved out a consistent niche behind Marshawn Lynch and was moved to the Cowboys.
He was waived by the Cowboys and picked up by Washington.
The Seahawks signed Brown with Rawls being placed on injured reserve following his season-ending ankle injury Sunday.
Carroll said Wednesday that Michael's familiarity with the system was the big factor in bringing him back.
Michael met with Carroll and general manager John Schneider Wednesday morning. Carroll said Michael was "very serious and very focused and wants to do something with this opportunity."
