49ers wide receiver Michael Crabtree was held out of Wednesday’s practice with a calf injury. His status for this week’s season opener is unknown at this point, according to CSNBayArea.com.
It’s the second leg injury for Crabtree from the start of training camp up to the 49ers’ first regular-season game. He sustained a hamstring injury that kept in out of action for 16 days during training camp. Crabtree’s availability for the regular-season opener on Sunday against the Dallas Cowboys is not known.
