Conor McGregor Says He'd Kill Mayweather In Seconds, Champion Has Surgery, UFC On Fox Weigh Ins

- Brash Featherweight contender Conor McGregor is no stranger to making headlines, but usually within the MMA world. This week, he had choice words for boxing king Floyd "Money" Mayweather.

"I don't look at a man who's expert in one area as a specialist," McGregor told Esquire. "I look at him as a rookie in 10 other areas. If you can box, what happens if I grab hold of your legs? If you put me face-to-face with Floyd Mayweather, pound-for-pound boxing's best, if I fought Floyd, I would kill him in less than 30 seconds."

We'll have full, live PPV coverage of Mayweather's fight against Manny Pacquiao on May 2.

- UFC Lightweight Champion Rafael dos Anjos underwent knee surgery this week to fix an injury he sustained while training for his UFC 185 championship bout. Despite having a partially torn MCL, dos Anjos dominated the former champion Pettis on his way to victory.

Dos Anjos says he's eyeing a fall return to the UFC, according to MMA Fighting.
