Bradford did very little in practice this week as the Rams tried to ease him along in the hopes of starting in Seattle. He sat out last week against San Francisco after suffering the injury in October against Green Bay.
The Rams were preparing Tom Brandstater to potentially make his first NFL start, but Brandstater was inactive and recently signed Kellen Clemens was Bradford's backup. The Rams were also without starting defensive tackle Fred Robbins.
The Seahawks won 30-13.
