With Schaub missing both Wednesday and Thursday's practices with a sore knee and shoulder, the Seahawks could face the same quarterback - Clausen - they beat earlier in the year when he was a member of the Chicago Bears.
With the Minnesota Vikings losing 23-20 to the Arizona Cardinals Thursday night, the Seahawks can swoop into the fifth seed of the NFC playoff hunt with a win Sunday over the Baltimore Ravens.
A Seattle win seems likelier with Baltimore potentially down to their third string quarterback. Jimmy Clausen, who the Seahawks beat while he was a member of the Chicago Bears, has taken the first team snaps the past two days with normal Ravens' backup Matt Schaub nursing a sore knee and shoulder.
