The trio were among six Seahawks that were injured in the win. Rookie right guard John Moffitt injured his right knee early, while defensive end Anthony Hargrove and backup safety Atari Bigby both left with hamstring injuries.
None of the six returned. Coach Pete Carroll said Moffitt would need an MRI on Monday, but didn't have updates on any of the others.
Baldwin was hurt late in the first half diving for a pass in the back of the end zone. Rice was injured midway through the third quarter as he tried to come down with a leaping deep pass from Tarvaris Jackson.
Chancellor had to be helped off the field in the fourth quarter when he collided helmet-to-helmet with Anquan Boldin. Chancellor was penalized for the hit.
