Anthony Spencer News: Spencer (knee) did not participate in practice Thursday, the Cowboys' official site reports.

Spencer (knee) did not participate in practice Thursday, the Cowboys' official site reports.

The downgrade may simply be to reduce Spencer's reps heading into the weekend but may also be due to a setback with the recovering nature of his surgically-repaired right knee. In any case, after fitting in his first activity Wednesday since undergoing surgery in late July, the defensive end's availability for Sunday's contest at Kansas City may be clarified, for good or bad, in the near future.
