Updating a previous item, coach Jim Harbaugh confirmed Michael Crabtree's Achilles' tendon was "completely torn" during Tuesday's OTA practice, and the injury was to Crabtree's right Achilles'. So this wasn't a partial tear like Terrell Suggs' April 2012 Achilles' injury. For bookkeeping, we like to know which side of Crabtree's body was injured, the full extent of the injury, and all dates associated with his recovery, in order to provide accurate timelines in the future. Crabtree underwent surgery on Wednesday, May 22. Per Harbaugh, the full Achilles' tear occurred when Crabtree was "coming in motion and just planted and started a route, and it felt like someone kicked him in the Achilles'." The 49ers hope to have Crabtree back around Week 12.
