Merriman is questionable for San Diego

San Diego linebacker Shawne Merriman is listed as questionable to play Sunday in a pivotal game at Dallas.

Merriman practiced fully Friday and Thursday after being limited Wednesday. Merriman has missed most of the past two games with a nagging foot injury. The fact he practiced fully to end the week may be an indication that Merriman will play at Dallas.

Defensive end Luis Castillo is probable to play. He practiced fully all week. He missed the past two games with a calf injury. Safety Eric Weddle is doubtful to play with a knee injury. He didn’t practice all week. He missed last week’s game and was expected to miss two games.

Center Nick Hardwick will miss his 12th straight game with an ankle injury.
