Receiver A.J. Jenkins played into the third quarter in Friday's exhibition win over the Chiefs but did not have a catch.
He was targeted twice, and like last week a long pass attempt from Colt McCoy to Jenkins resulted in an easy interception by the opposition. McCoy tried to hit Jenkins streaking down the sideline, but the receiver was blanketed by big cornerback Sean Smith, who picked off the pass.
Jim Harbaugh said he thought Jenkins had a step on Smith on the play and that McCoy's throw "should have been out in front of him, not over the back shoulder." Said Harbaugh of Jenkins: "I thought he did okay."
Like last week, Anquan Boldin and Marlon Moore (Natomas High) started at wide receiver but left the game after the opening series. Chad Hall played one more snap than Jenkins and was the only wide receiver to make a catch, a 21 yarder from Scott Tolzien, in the first half.
Jenkins had a 21-yard completion early in the third quarter, but it was wiped out by a holding penalty against backup center Daniel Kilgore.
Craig Dahl started his second straight game at free safety alongside Donte Whitner. Dahl, first-round draft pick Eric Reid, C.J. Spillman and Trenton Robinson had been alternating practice repetitions with the first-team defense in training camp.
Et cetera -- Fourth-round draft pick Quinton Patton was in uniform for pre-game warm-ups, signaling that the wide receiver might be close to returning to full-time status. Patton damaged the forefinger on his left hand before training camp opened, and while he has been able to run routes at practice, he was instructed not to catch passes. Neither Patton nor receiver Kyle Williams played Friday. Williams indicated, via Twitter, that he would be back for next week's game against Minnesota. he's been dealing with a hamstring injury.
* Joe Staley, who missed four practices in the run-up to the game with an undisclosed injury, started at left tackle. Staley left the game later in the first half as a precaution and was replaced by Adam Snyder. Harbaugh said he was not aware of any injuries in the game.
* Jewel Hampton was the third tailback to enter the game after Frank Gore and LaMichael James. Hampton, who did not play last season, finished with 33 yards on 19 carries (1.7-yard average) and caught two passes 17 yards. Hampton aid he strained his hamstring two days before the preseason opener against Denver, which is why he didn't play in that game.
* As was the case last week against Denver, an inside linebacker led the 49ers in tackles. Moody had 10 stops; Michael Wilhote led the team last week.
* Why didn't Colin Kaepernick play more than one series? "I think we're good with Colin; we know what we've got (in him)," Harbaugh said. "In the second week of preseason we didn't want anything freakish to happen to him."
