Michael Crabtree's right ankle injury is not related to the foot problem that has plagued him since coming out of Texas Tech. The foot Crabtree had surgically repaired before the 2009 draft was his left, and the most recent issues are with Crabtree's right foot. "Like any injury, you never know how long it's going to take these guys to come back," GM Trent Baalke said Sunday. "But he's working hard at it. The prognosis looks good."
