The team listed its Pro Bowl linebacker as inactive against the Seattle Seahawks. That is no surprise after Willis practiced on only a limited basis while recovering from a hamstring injury. The team needs him for the playoffs.
Receiver Braylon Edwards, inactive for the 49ers against Pittsburgh last week, is active and starting.
Return specialist Ted Ginn Jr. is also inactive for the 49ers. Ginn scored twice on return touchdowns against Seattle in Week 1. He has helped the 49ers lead the NFL in average starting field position this season. His absence leaves the team less experienced and less dynamic in the return game.
For the Seahawks, receiver Doug Baldwin is active despite an ankle injury, consistent with what coach Pete Carroll said he expected. Baldwin injured the ankle in practice Wednesday. He's the best receiver on the active roster and a player the Seahawks rely upon during critical situations, including third down. Having him active was especially important with Sidney Rice and Mike Williams on injured reserve.
