Coach Mike Singletary said on Thursday that Crabtree would play approximately one quarter. Crabtree had returned to full practice after missing nearly two weeks with a neck strain.Tight end Vernon Davis (right knee strain) and cornerback Shawntae Spencer (hamstring) did not play. Also, left tackle Joe Staley played one quarter before leaving with a right knee sprain. He appeared fine on the sideline, standing and walking without a limp.The game also featured the exhibition season debut of running back Frank Gore. He tore off on a 49-yard run the first time he touched the ball. But that drive eventually stalled when he mishandled a pitch from quarterback Alex Smith.Smith completed 9 of 15 passes for 113 yards and touchdown. He tossed a 16-yarder to Josh Morgan, who had three catches for 31 yards in the first half. Gore had two rushes for 58 yards. Here's what Gore had to say, courtesy of the 49ers' public relations department:On how it felt to get back out there: "It feels great man, especially going through training camp all month and I didn't get to go against another team. I was like a little kid out there. I was happy.On the 49-yard run: "Our O-Line and (fullback) Moran Norris, they did a great job and the receivers did a great job down field, and it was there and I hit it. I was patient, I was patient and I exploded through.On how comfortable he feels on the field: "I feel great, man. Coming off a great camp, you know, I'm happy to be out there. My new O-linemen (left guard Mike) Iupati, (right tackle) Anthony Davis, and you know my old boys, they have all been doing a great job up front too. You know, we just have to keep working and get ready for the first game.On how it felt to run behind Iupati: "It was wide open. He's a big guy, a wide space so they can't see you behind him and I was there, waiting for the hole to open and I just hit it."On what happened when he fumbled: "You know, I saw touchdown. I didn't look the ball all the way in, I was looking up the field because I saw a touchdown and the ball slipped. It's something that won't happen in the regular season."
