There was a rumor floating around that Floyd Mayweather Jr's crew was responsible for breaking Javon Walker's orbital bone and robbing him. This rumor probably came out as Floyd and Javon were spraying thousands of dollars worth of champagne at Tryst earlier.  In any case, here's Javon's story:

...In an exclusive statement to The Dirty.comWalker said, "I was just back at my room and at about 5:30 in the morning, I got a knock at the door, I opened it and 3 guys with guns were there, they cracked me in the head a few times knocking me unconscious. They then robbed me of everything I had -- my watch, money -- everything! Somehow they got me to the car and dropped me off in the street. That's what happened."

... also says reports that the robbery stems from the champagne wars with Floyd Mayweather at Tryst nightclub earlier in the evening are completely false.
