Christian Kirk is out vs. the Raiders with a meniscus injury that may need surgery
Kyle Shanahan said Christian Kirk injured his meniscus and is out Sunday against Las Vegas while the 49ers still do not know if surgery is required.

San Francisco's receiver depth took another hit Friday.
Coach Kyle Shanahan said wide receiver Christian Kirk is out for Sunday's game against the Las Vegas Raiders after injuring his meniscus earlier in the week. Shanahan said the team does not yet know whether Kirk needs surgery.
Kirk had only recently worked his way back into the mix after a calf injury that put him on injured reserve out of training camp.
Thin at receiver
Mike Evans (ribs/Achilles) and Deebo Samuel (hamstring) are also out Sunday. Demarcus Robinson (ankle) is questionable. Christian McCaffrey is off the injury report after a hamstring issue.
Evans has not played since Oct. 19. Samuel has been out since Oct. 11.
Bosa expected back
Defensive end Nick Bosa (knee/calf) carries no injury designation and is expected to play for the first time since hurting his calf in Week 3.
The 49ers (6-1) host the Raiders on Sunday afternoon at Levi's Stadium.
