Mathieu (shoulder) did not participate in practice Thursday, Darren Urban of the team's official site reports.

After practicing in a limited fashion Wednesday, Mathieu took a step back on Thursday as he remained on the sidelines nursing his injured shoulder. Look for more updates to come after Friday's practice. Should he be ruled out of Week 13's tilt with Washington, look for D.J. Swearinger to get the spot start.
