The Seattle Seahawks re-signed running back Demitrius Bronson and claimed center Patrick Lewis off waivers on Wednesday.
The Seahawks also released linebacker Marcus Dowtin and guard Greg Van Roten.
Bronson returns to the team after being released on Aug. 25.
Coach Pete Carroll said Bronson was re-signed after Christine Michael hurt a hamstring in practice on Tuesday that will keep him out of Thursday night's final preseason game at Oakland.
"Christine Michael pulled up a little bit yesterday in practice so we're just insuring we have enough guys to run the football," Carroll said. "He (Bronson) did a real nice job when he was here, but numbers just caught him at the cuts."
Lewis entered the NFL in 2013 as a rookie free agent with the Green Bay Packers, but was released on the final roster cut last August. He was claimed the next day by the Cleveland Browns, who then released him in November and signed Lewis to their practice squad. The Jacksonville Jaguars signed him off the Browns' practice squad last December before releasing him.
Dowtin signed with Seattle on Aug. 1 and Van Roten signed a future contract with the Seahawks on Feb. 14.
