Running back Fred Jackson and cornerback Marcus Burley were both forced from Monday's game against the Detroit Lions due to injury.
Jackson suffered a sprained ankle when a Detroit defender landed on the back of his right leg. X-rays were negative, but Jackson will undergo an MRI exam on Tuesday.
Fantasy Impact:
The Seahawks are hopeful to get Marshawn Lynch back for Week 5, saying he was close in Week 4. Thomas Rawls should also be available if Jackson can't go but isn't much of a pass-catching option.
