The Raiders and 49ers will practice against each other for the first time on Monday in Napa. Mike Nolan likes joint practices and he approached the Raiders this year, and they agreed, as long as there wasn't live tackling. "Not that guys back off (in regular practice), but you know what you're going to get," Nolan said. "A game isn't that way. When you go into a game, you feel guys out. There's the unexpected."
