Jim Harbaugh was looking for a crisper, sharper practice today after Saturday's slop-fest at Candlestick Park, and he got it. Colin Kaepernick and Vernon Davis were clicking on the deep pass once again while Kyle Williams also looked good. Williams has been coming back from a hamstring strain and sat out Thursday's preseason opener. Judging from today's practice, he's likely to play - and start? - in Kansas City. Williams caught three passed from Kaepernick, including a deep route down the middle that hit the receiver in stride.
One of Kaepernick's deep throws to Davis was the same type of corner, post-route that has been so effective in earlier practices this summer. The duo beat cornerback Carlos Rogers and safety Craig Dahl on the play. The second one was one of the most impressive throws of camp. It traveled about 40 yards and victimized inside linebacker Michael Wilhoite, who was covering Davis off the line of scrimmage, and safety Donte Whitner, who had him deep. What stood out is that the ball never got above nine feet off the ground. It was an absolute laser-cannon-frozen-rope that Davis snagged just above his head.
A.J. Jenkins had been taking the lion's share of the practice when it comes to the wideouts. However, he had a quiet afternoon today. He caught one short pass along the sideline late in practice.
The best catch of the day was turned in not by a wideout or tight end but by running back Frank Gore. During a red-zone drill, Kaepernick was flushed to his right and looked like he would have to run, at full sprint, out of bounds. At the last moment, he flung the ball into the end zone and Gore, also running to his right, made a diving catch.
Receiver Austin Collie also made a diving catch along the sideline on a Colt McCoy - he was out of his blue, non-contact jersey -- pass that seemed as if it would drop harmlessly incomplete. Collie had a good day working out of the slot, and he caught a red-zone pass in the end zone from Scott Tolzien ... Kaepernick also hit Chad Hall streaking across the back of the end zone for a touchdown.
Cornerback Tarell Brown did not practice with what seems to be a minor injury while Tramaine Brock had a very light session just as he did Saturday. That meant that Nnamdi Asomugha was one of the first-string cornerbacks (right side) with Carlos Rogers (left side) and that Perrish Cox took over for Rogers in nickel situations.
It also meant that undrafted rookie Darryl Morris saw a lot of action with the second-team defense. Morris had a strong day at right cornerback. He picked off a B.J. Daniels throw along the sideline and also broke up a pass in the corner of the end zone intended for the much bigger Ricardo Lockette.
Eric Reid was back after sitting out most of Saturday's practice, but another high draft pick, Vance McDonald, was absent. The tight end practiced sparingly on Saturday. Joe Staley, Jewel Hampton and Ray Ventrone also missed practice, all with what are believed to be minor injuries. ... The starting safeties were Dahl and Whitner. Reid and Trenton Robinson played with the second-team unit.
Nose tackle Lamar Divens was out of the blue, non-contact jersey he was wearing Saturday.
