Marshall signed with the Seahawks on Thursday, Bob Condotta of the Seattle Times reports.

EDGE Analysis

Marshall was undrafted out of Arizona State in 2013 and has played the past three seasons in the CFL. Last year, with the Winnipeg Blue Bombers, he ran for 614 yards and five touchdowns, and totaled 378 yards and two touchdowns receiving. The Seahawks have seven running backs on the roster after signing Marshall, but three are injured at present. He'll look to slide in as the fourth option until the others are able to return.
