Frank Gore wants to see more maturity out of Vernon Davis, and he told him so.
"It's his fourth year now. Now it's time," Gore said Saturday.
The 49ers running back spoke to reporters a day after Davis said some of his teammates were upset by his latest training camp fight. Coach Mike Singletary punished the entire team after Davis' scuffle by making players run sideline-to-sideline sprints.
Gore was among those unamused.
"I wasn't mad about having to run gassers," he said. "I just feel it's his fourth year now, and I told him it shouldn't be him now. Everybody makes mistakes but it shouldn't be him. OK, a rookie? I accept that."
Gore and Davis have a friendly relationship and joke around frequently in the locker room. Before talking to reporters Saturday, Gore said he had already spoken to the tight end about the matter, telling him: "It's time to be a man and try to do everything right. There are younger guys who probably look up to you on the team."
Davis, 25, has a history of training camp fights. He vowed to dial it back this season, but on Thursday he tussled briefly with linebacker Marques Harris.
Singletary held Davis accountable for the incident and pulled him aside for a one-way conversation.
Then, the coach made everyone run.
Davis said of that experience: "A few guys were mad, but like I told them, you can't get mad because there will be time you make the rest of us run. I told them they should be happy that I made them run because it's extra work for us and a chance for us to get better."
The 49ers' receiving corps competition is so wide open, only Isaac Bruce is guaranteed a roster spot, Jimmy Raye said. The offensive coordinator said Bruce "has shown me nothing to deter what I thought about him prior to coming here."
Everyone else, apparently, is on the bubble. First-round pick Michael Crabtree remains unsigned and Brandon Jones is out for two months with a shoulder injury. The other receivers in camp are Josh Morgan, Jason Hill, Arnaz Battle, Dominique Zeigler, Micheal Spurlock, Mark Bradford, Dobson Collins, Maurice Price and Chris Francies.
Among the injured players who did not practice Saturday: LB Patrick Willis (ankle), CB Tarell Brown (toe), RB Michael Robinson (groin), TE Delanie Walker and G David Baas (foot). ... As if to dispel questions about his arm strength, quarterback Shaun Hill connected with Battle, who made a tumbling catch in the end zone for a 40-yard touchdown during the morning session. During the afternoon session, he hit Davis for a 60-yard touchdown.
