The Facts: According to ESPN's Adam Schefter, the 49ers have activated McKinnon from the Active/Physically Unable to Perform List.

Diehards Line: McKinnon has spent the last year rehabbing from a torn ACL suffered in training camp last summer. His progress is worth tracking. Remember, the Niners made him the fourth-highest paid RB in the NFL as a free agent last year. Clearly they like him. Whether he can rebound and make good on that remains to be seen. But he'll jump back into the fray with Tevin Coleman and Matt Breida for snaps in the offense.
