Canseco and Sapp trade barbs, look to be spoiling for a fight

Jose Canseco is always ready for more publicity and more cash - and he's managed to dredge up both with a few pay-per-view MMA celeb fights. He's got one planned against Shaquille O'Neal but wants one before that with former NFL great Warren Sapp, who apparently irked Canseco recently when he called Canseco's friend, Jeremy Shockey, a snitch. Sapp accused Shockey of spilling the beans to the NFL about the bounty system going on in the New Orleans Saints locker room that had players earning extra cash for making devastating hits. Sapp and Canseco jawed at each other via Twitter this weekend and it's looking like they could be spoiling for a fight. May the most publicity-hungry man win.
