Coach Jim Harbaugh said it's "possible" Michael Crabtree (foot) will practice this week. "We'll see," a taciturn Harbaugh added. Braylon Edwards has taken over as the Niners' No. 1 receiver in Crabtree's absence. It remains to be seen how the snaps will be broken down once Crabtree does return, but we expect a slow start regardless. Crabtree is more of a WR4 candidate this year.
