Thomas separated the shoulder during the NFC Championship Game but returned to finish out the victory and started in the team's Super Bowl XLIX loss to the New England Patriots.

Thomas is the third member of the Seahawks' vaunted defense known to have played through a worse-than-expected injury during the Super Bowl. Strong safety Kam Chancellor played with a torn MCL and cornerback Richard Sherman may need Tommy John surgery on his left elbow.
