RENTON, Wash. (AP) — The Seattle Seahawks have signed former second-round draft pick Christine Michael to bolster an offensive backfield thinned by injuries to Marshawn Lynch and Thomas Rawls.

Coach Pete Carroll announced Michael's signing Wednesday. The Seahawks traded Michael to Dallas at the end of training camp after he lost out to Rawls for the backup spot to Lynch.

Michael's return is a surprise after the trade seemed to cut all the ties with Seattle. He was drafted in 2013 with the idea that he could eventually be Lynch's replacement but never matched the potential he flashed at Texas A&M. Michael had 52 carries for 254 yards in his two seasons with Seattle. Michael appeared in five games with Dallas this season and had 51 yards on 15 carries.
