The Facts: Crabtree sat out during the 49ers' non-padded practice on Thursday one day after leaving the field early due to an apparent lower leg condition.

Diehards Line:Crabtree took part in individual and one-on-one drills during practice Wednesday afternoon. He did not sustain any noticeable injury. At one point early in practice, a 49ers athletic trainer tended to Crabtree as he sat on the ground. A short time later, Crabtree walked back to the 49ers’ locker room by himself. There is no word from the 49ers on Crabtree’s condition. Whatever it is doesn't sound serious. But we'll follow up as further details come to light.
