A pair of high-profile NFC West wideouts missed most of the season before returning from injury. For Seahawks receiver Percy Harvin, it was a one-game cameo before again being shelved with the same hip injury. For 49ers receiver Michael Crabtree, he has a different injury after two games back.

Crabtree has an ankle injury. He was officially limited in practice on Wednesday because of it.

According to Bill Williamson of ESPN.com, 49ers offensive coordinator Greg Roman said Thursday that the ankle problem is unrelated to the Achilles injury that kept Crabtree out of action from May until Week 13.

Crabtree caught two passes for 68 yards in his 2013 debut against the Rams. He had four catches for 40 yards against the Seahawks.
