SANTA CLARA -- In the wake of a string of injuries and Friday's physical practice, coach Jim Harbaugh apparently had seen enough. Harbaugh stopped practice with about 40 minutes remaining Sunday and ordered cornerback Chris Culliver out of a drill following his hit on wideout David Reed.
Harbaugh reminded his team to not make unnecessary hits, to play clean and to support each other.
Culliver angrily headed to the sideline, where he watched the remainder of practice. But Harbaugh walked with him to the locker room and Culliver calmly listened as the coach talked during that 30-second stroll, ending with Harbaugh opening the door for him and other players.
Culliver has lined up all camp as the first-string right cornerback and is slated to start for the first time in his four-year career. Coming off a knee injury that sidelined him all of last season, he's looked fine, and judging from his actions Sunday, he still has that competitive edge that helped him serve as the nickel back in 2011-12.
Several veteran leaders came to talk with Culliver after he got ejected from the 11-on-11 session, including Vernon Davis, NaVorro Bowman, Aldon Smith and Ahmad Brooks.
