Summary: The 49ers' only open practice of training camp began on an ominous note when tight end Delanie Walker went down during the first 11-on-11 period with a right knee injury while in pass protection.Walker, with some assistance, eventually made it to the 49ers' bench at Candlestick Park. He watched the remainder of practice sitting down with his right leg elevated. He had ice on his right knee, and later wore a brace."We'll wait until we get some further results from the doctors, but I think we'll dodge another bullet there," Harbaugh said, indicating Walker is not expected to be out for a significant period.RELATED: Delanie Walker career stats 2011 game logs
The 49ers announced 32,000 fans attended the daylong Fan Fest event, which concluded with a 2 12-hour practice and half-hour autograph session. Harbaugh was the final person signing autographs.
The final period of practice was an 11-on-11 session in which the offense was given the ball at the opposition's 8-yard line with 4:54 remaining on the clock.
Alex Smith led the offense down the field on a 17-play drive that was capped by his 14-yard touchdown pass to tight end Konrad Reuland against the coverage of Patrick Willis. On the drive, Smith completed 10 of 11 passes for 79 yards on the drive. He ran two quarterback sneaks to pick up first downs on third-and-1 situations. The big offensive play was an 18-yard pass to Kendall Hunter. The defense's best play was Demarcus Dobbs sack (with just a touch) after center Jonathan Goodwin's bad snap to Smith in the shotgun formation.After the offense won the drill, that unit was rewarded with four windsprints. That's right, the winner ran -- not the losers. And the reasoning behind that?
"The winners get to get better," Harbaugh said. "They get that opportunity."Cornerback Carlos Rogers jumped in and ran sprints with the offensive players.Injury report: Outside linebacker Aldon Smith is expected to miss more than a week with a right hip bruise, Harbaugh said. Smith sustained the injury in the first quarter of the 49ers' exhibition opener against the Minnesota Vikings. Smith might not play again in the exhibition season, but he is expected to be ready for the opening of the regular season on Sept. 9 at the Green Bay Packers. . . . Rookie outside linebacker Cam Johnson, who did not suit up for Friday's game, did not practice due to an undisclosed injury. Johnson has not looked up to speed during camp after undergoing arthroscopic surgery before camp. . . Receiver Joe Hastings (right leg) rehabbed and appears to be close to returning to practice after missing more than a week. Tight end Nate Byham and offensive lineman Garrett Chisolm also did not participate in practice. . . Running back Jewel Hampton (foot) is on the non-football injury list, while outside linebacker Darius Fleming (knee) is on the physically-unable-to-perform list.Returning to work: Running back Frank Gore, receiver Mario Manningham, and defensive linemen Justin Smith and Will Tukuafu practiced Sunday after being held out of Friday's game.Offensive play of the day: During a red-zone drill, quarterback Scott Tolzien drilled a 6-yard pass into the back left corner of the end zone to Manningham, who went up to catch the pass before cornerback Tramaine Brock could turn around to make a play.Defensive play of the day: Earlier in the practice, Tolzien attempted a pass to Moss (or rookie A.J. Jenkins), and Rogers was in the right spot to intercept the pass. The only other interception during 11-on-11 work was courtesy of Cory Nelms, who picked off Josh Johnson's pass after it deflected off Reuland's hands.
Eye on the stands: First, receiver Randy Moss played whipped the fans behind the 49ers' bench into a frenzy during a down period devoted to special teams. Moss threw the ball into the stands, asked for the ball back and threw it to someone else. He did that for several minutes. He autographed at least one ball thrown to him and tossed it back.During practice, a scruffy-looking, shirtless fan ran onto the field and approached Harbaugh, he seemed none-too-amused with the intruder. "I didn't say anything," Harbaugh said. "I'm glad he was clothed. I'm glad he wasn't naked." The trespasser left the playing field, but was taken down by security and handcuffed.
Notable: Tight end Vernon Davis wore No. 87, instead of his familiar No. 85 during practice. So was he paying homage to Dwight Clark, whose number has been retired? Not exactly."I'm sorry, Dwight," Davis said. "We were in a rush, me and some of the other guys, and we forget our jerseys. This is the only one they had for me. . . . This jersey. This is history right here. It feels good to wear No. 87."Transaction report: On Saturday, the 49ers signed outside linebacker Kenny Rowe and released safety Mark LeGree. Rowe will not be allowed to wear pads and go through team drills until Tuesday while he goes through a mandatory period to get acclimated to camp.
Quotable: "I didn't expect so many people to be here. In the past, it hasn't been this many people. But for them to come out, it shows how much effort they give to support us. We greatly appreciate that" -- Vernon Davis.Next practice: The 49ers return to practice Monday from 2:30 to 5:10 p.m. The 49ers will break camp after practice on Friday.
