articleThe Brief The Seahawks are listing cornerback Devon Witherspoon as doubtful to play for Sunday's game against the Steelers due to a knee injury. Seattle Seahawks cornerback Devon Witherspoon is doubtful to play against the Pittsburgh Steelers on Sunday due to a knee injury. Safety Coby Bryant collided with Witherspoon’s knee while Josh Jobe was making an interception of a Brock Purdy pass. Macdonald said he doesn't believe Witherspoon's injury will be a long-term issue, which is good news for Seattle. He then sustained a torn thigh just 20 snaps into his first game back from the knee injury and was sidelined again.
