Some 49ers notes from Saturday's practice:
- QB Colin Kaepernick had an uneven practice, but when he was on, the results were pretty. Such as the time he hooked up with WR Torrey Smith deep down the right side, beating Marcus Cromartie on a particularly nice throw. But Kaepernick also seemed to revert on a couple of passes, such as the deep ball down the left side that wobbled as it approached Bruce Ellington, giving Kenneth Acker time to react and knock it down. Smith also had an acrobatic one-handed grab on a Kaepernick out pass to the left sideline.
- Someone who did not necessarily shine? Tight end Vernon Davis, who had a drop and also a miscommunication with Kaepernick. Davis was still running in the middle of the field and looking toward the end zone as the ball landed at his side.
- Running back Reggie Bush was held out by coach Jim Tomsula after the rookie coach saw the 10th-year veteran getting in some extra stretching. "I'm not going to wait to see Reggie tired and (then) give him a break," Tomsula said. "He's been doing this for a long time. Our goal is to not get Reggie tired. He's in shape."
