Russell Okung and Max Unger participate in Seahawks' practice

RENTON, Wash. -- The Seattle Seahawks had a little bit of good news on the injury front when left tackle Russell Okung was a full participant and center Max Unger was a limited participant in practice Wednesday, leaving some hope that Unger could play Sunday against St. Louis.

Okung, who missed last weekend with a bruised lung, is expected to return Sunday.

Unger has missed the past five games with a high-ankle sprain. The Seahawks will have to weigh whether to play Unger Sunday or hope they win against the St. Louis Rams, which would mean Unger could heal up until the second weekend of January for what would be Seattle's first playoff game.

As expected, wide receiver Jermaine Kearse (hamstring) and cornerback Tharold Simon (shoulder) did not practice and are not expected to play Sunday.

Also missing practice Wednesday were tight end Cooper Helfet (ribs), defensive end Demarcus Dobbs (ankle), wide receiver Chris Matthews (hamstring) and running back Marshawn Lynch, who always rests his back on Wednesdays.

Tight end Tony Moeaki, who didn’t play at Arizona because of a shoulder injury, was a full participant in practice Wednesday.
