What happened: Outside linebacker T.J. Watt carries a questionable designation after participating on a limited basis during Thursday's practice in Pittsburgh. Head coach Mike McCarthy said he does not expect the ailment to keep the edge rusher out of Sunday's lineup.

Why it matters: Having Watt available preserves the pass-rush and run-stopping anchor for a defense riding a two-game winning streak as the No. 6 seed. Even while managing the calf issue, Watt has graded out as one of the league's top run defenders this season.

What to watch: Friday's final injury report will clarify whether Watt upgrades to full participation ahead of Sunday's game in Paris.
