Seahawks rookie running back C.J. Prosise is among Seattle's inactive players Sunday versus the Los Angeles Rams.
Prosise, 22, suffered a broken bone in his hand/wrist in the Seahawks' Week 1 victory over the Miami Dolphins and was a game-time decision.
In his place fellow rookie Alex Collins will suit up for the first regular-season game of his NFL career. The fifth-round pick will likely be the team's third running back behind starter Thomas Rawls and backup Christine Michael.
First-round guard Germain Ifedi (ankle) is inactive for the second-straight game, as is third-round tight end Nick Vannett.
