Per USA Today's Mike Garafolo, 49ers receiver Michael Crabtree tore his Achilles during organized team activities yesterday. A source also told Garafolo that Crabtree will soon have surgery, and that the injury could be serious enough to keep Crabtree from playing this season.

The Niners haven't yet commented on the situation. Two reasons for Crabtree to be hopeful: The Ravens' Terrell Suggs and the Bucs' Da'Quan Bowers both tore their Achilles last spring but eventually managed to play last season.
