Injuries are suddenly piling up fast for the San Francisco 49ers in training camp.
All-Pro linebacker Patrick Willis was wearing a black cast around the base of his right hand and wrist and was among more than a dozen players not participating in practice Thursday. Barely 45 minutes into the workout, trainers carted cornerback Chris Culliver off the field with an apparent left knee injury.
Willis injured his hand during one-on-one blocking drills Wednesday. He stood on the sidelines the rest of practice with his wrist and hand heavily wrapped.
Culliver's injury appeared even more serious. He was covering a punt in a non-contact drill when he went down in pain. He held his left knee and buried his head in his hands before being taken off the field.
