Kurt Warner visited the 49ers on Monday, meeting with the team's front office and undergoing a physical. San Francisco general manager Scot McCloughan was thrilled that Warner took the time to visit. "It's still up in the air," McCloughan said. "We're very excited he's willing to come visit us and possibly be a 49er. ... He's a very classy guy, and you can see why he's been so successful in his career, the way he carries himself."
