NEW ORLEANS -- San Francisco 49ers quarterback Colin Kaepernick throws the football with tremendous velocity, as Randy Moss' dislocated finger can testify.

Baltimore Ravens cornerback Corey Graham provided independent witness testimony Tuesday during Super Bowl media day at the Superdome.

"It's funny you say that," Graham said. "I didn't know if I was seeing things or not, but when I watched him on film, the ball got there very fast."

Moss picked it up from there.

"For him to dislocate my finger and for the doctor to pull it out, I've never had no problems with my fingers before," Moss said. "You have a shoulder here, an ankle here, a knee here and that comes with the territory. For me to be catching balls my whole life and then all of a sudden my finger pops out of place, man, I've never experienced that and it hurt like hell."

Moss suffered the finger injury while catching a pass from Kaepernick during the quarterback's first NFL start, a 32-7 victory over Chicago in Week 11. With that play in mind, I asked Moss if he cranked up the 'Jugs' machine to simulate Kaepernick's velocity. He said it's no use because the machine can't deliver the ball as hard as Kaepernick throws even on its highest setting.

"I mean, it's hard to really explain, man," Moss said. "I really think the only way you can experience how hard he throws is if you put a pair of gloves on and go out here and play catch with him."

Kaepernick played baseball competitively and could throw a fastball 90 mph, and then some.

"One of our equipment managers, Doc, sometimes he doesn't even wear gloves and he catches 'Kap' to warm him up," Moss said. "And then sometimes I feel sorry for him that I'll go up and catch a few balls just to let his hands rest. And then once he heat mine up, 'All right, Doc, it's all yours.'

"I mean, Kaepernick is an incredible talent, man. I remember early in Brett Favre's career when he broke a couple fingers, but he broke them out in the tundra, I think, because it was cold. 'Kap' breaking fingers in 60- and 70-degre weather. I'm a big fan of Kaepernick's and it's fun to play with him."
