The wide receiver, practicing only once a day after offseason toe surgery, will undergo an MRI on Tuesday evening and be further examined Wednesday. A source said early indications are positive concerning Nicks' knee, but more will be known later. The team announced that his status might not be updated until Thursday morning.
Nicks appeared to injure his knee at the end of the afternoon practice and was able to walk under his own power before riding a cart from the field to the locker room.
The team did get some good news when an MRI exam revealed no new damage to Shaun O'Hara's swollen left ankle. The starting center left camp on Tuesday to travel to Manhattan to undergo an MRI and X-ray at the Hospital for Special Surgery. The team said O'Hara's swelling is a result of "a chronic condition in the joint, which is being treated to reduce the swelling and regain the mobility."
Also, wide receiver Mario Manningham sat out both practices with a groin issue. Tight end Travis Beckum did not practice with a sore hamstring and safety Kenny Phillips (knee) and guard Kevin Boothe (pectoral) are already on the physically unable-to-perform list in camp.
