UFC Champ Chris Weidman Poses with Less-Than-Happy Floyd Mayweather

Chris Weidman had quite the weekend, but his fun didn't end on fight night. The UFC middleweight champ took to social media Sunday night to post photos of a chance encounter he had with boxing great Floyd Mayweather Jr. Via Weidman's Twitter account:

Weidman was in Las Vegas on Saturday night to face title challenger and longtime rival Vitor Belfort in the co-main event of UFC 187. While Belfort clipped Weidman in the early goings of the bout, staggering him with punches and knees along the cage, Weidman was able to post an impressive victory by scoring a perfectly timed takedown, quickly moving to mount and pouring on heaping helpings of ground-and-pound. The win gave Weidman his third title defense and extended his career record to 13-0. 

Mayweather (48-0 in his boxing career) has also been quite busy of late—as you can obviously tell by the completely disinterested face he has in the picture. In May, Money faced Manny Pacquiao in the single biggest match in the history of boxing. While casual fans panned the fight as boring, there was no debate regarding how lucrative it wound up being for both men and the state of Nevada, as the event raked in an estimated 4.4 million buys (according to Dave Meltzer of MMAFighting.com).

Weidman isn't the first UFC champ to pal around with Mayweather. Then-bantamweight champ Dominick Cruz spent a fair bit of time with him in 2013, picking his brain for combat sports wisdom. 

At this time, Mayweather is angling for a retirement fight in September opposite a yet-to-be-named opponent. Weidman, meanwhile, is likely to defend his middleweight strap from either Ronaldo "Jacare" Souza or Luke Rockhold later this year.
