It started out as a spirited practice, but then settled down so both teams could get their work done.
"The competition is there," said Raiders head coach Tom Cable. "It gives you a chance to really dial in fundamentally who you are as a football player, and that's really what we've stressed."
"Just looking at the matchups and I thought we got some good work in," said 49ers head coach Mike Singletary.
Cable shut down any questions about the report he broke assistant coach Randy Hanson's jaw.
"Nothing happened," said Cable.
But his players joked about it.
"Yeah, you know, we knock each other out once a night… no, it's crazy, you know, I have no idea what happened," said Raiders offensive tackle Robert Gallery. "I could really care less."
Good news for the Raiders is that quarterback Jeff Garcia was back, and it was a bit surreal practicing against his former team.
"To be back out here and go against them again, it's a great thing in a lot of ways," said Garcia. "Get to see some old faces."
The bad news is that wide receiver Chaz Schilens, who was having a great camp, broke the fifth metatarsal bone in his left foot and will be out at least a month.
"It was a sharp pain, so that's all it is and I couldn't run anymore so I knew something was wrong," said Schilens.
Forty-niner rookie fullback Brit Miller was a bit amazed facing the Raiders in practice.
"It was fun just to see guys competing and just see some guys that you watched on TV last year, and just those sorts of things, and see what they go through on a daily basis," said Miller.
These two days of intense practices at Napa set up Saturday's game between these two teams at Candlestick Park.
