San Francisco 49ers WR Mario Manningham (knee) is scheduled to undergo an MRI on his knee. Manningham was forced from Sunday night's game with what looked like a painful knee injury--so painful he threw the ball away to clutch his leg.
Mario Manningham to undergo MRI on knee: Fantasy implications
Mario Manningham will have an MRI to determine the severity of his knee injury. We break down the fantasy implications.


X-rays revealed no fracture, but the team is more worried about ligament damage.
Fantasy Impact: The Niners haven't ruled out Manningham for Week 17 or the playoffs yet, but it would be a surprise if he didn't tear something. Assuming Manningham won't be playing for a while, SF may be forced to dress rookie A.J. Jenkins again.
For fantasy owners who are playing into Week 17, Manningham can be safely left on the bench against the Cardinals.
