T.I. -- I Can Take On Mayweather Just Fine

T.I. wants to make it clear ... he can stand up to Floyd Mayweather Jr.

T.I. posted this video on Instagram after his fight with Floyd at a Vegas Fatburger early Sunday AM.

There were reports Floyd gave him 2 black eyes, but the video shows his lids are clear. His hand, on the other hand, is f-d up. It appears he'd like us to believe it's from whupping some Floyd ass.
