CSN Bay Area says Michael Crabtree's return to game action will depend on how sharp he looks in practice. The Niners aren't going to strap a target date to Crabtree's back. Now that he's been cleared to resume practice, they'll take a look at how effective he is coming off a May full Achilles' tendon tear and play it by ear. Barring a setback, he'll appear in a game no later than Week 13. Stashers should note that Crabtree will face Richard Sherman/Brandon Browner in Week 14 and Darrelle Revis in Week 15.
