For this weekend in sports, we're guessing a lot of people expected Floyd Mayweather to walk away as the winner, Knicks over the Celtics, and probably Thunder winning over the Grizzles.

He straight up threatened Canseco on tweets he's since deleted, but you can check them out in the thumbnails.

Yep, he went there. Canseco responded by saying he's more than welcome to fight O'Neal, but hopefully it doesn't escalate into that.
