Floyd Mayweather’s next fight isn’t until September, but the undefeated boxer got an unexpected tune-up Sunday morning in Las Vegas. <br /> <br />Mayweather and rapper T.I. got into it at Fatburger on the Las Vegas Strip, according to TMZ, where chairs and fists were flying in the early-morning hours. <br /> <br />Two videos from the scene — one before the fracas and another during the row — show tensions escalating with Mayweather shouting, presumably at T.I., “control your b---- motherf-----.” A second clip shows the chairs flying through the Vegas grub hub, a spot Mayweather swears by. <br /> <br />Witnesses told TMZ that T.I. approached Mayweather while he was eating and started mouthing off. The website also reports that T.I. took a swing at Mayweather. Cops reported one minor injury and an uncooperative witness at the scene.
