Dana White has launched an incredible attack on fellow combat sports heavyweight Bob Arum, after the veteran boxing promoter enraged the UFC boss with some explosive comments about MMA.
Arum, 84, attacked MMA earlier this week at a press conference for Sunday's Terence Crawford v Viktor Postol bout at the MGM Grand, with drug issues high on his hitlist after UFC 200 was tainted by positive PED tests from superstars Jon Jones and Brock Lesnar.
"I don't think (drug testing) is particularly necessary as far as fighters are concerned," Top Rank Boxing supremo Arum said.
"Most fighters obey the rules. It's probably more necessary in MMA because they appear to be unconcerned with the testing. What the hell? As long as the tests come out after the fight, right? Everybody's collecting money. Just saying. just saying.
"You've got MMA, just sold for billions of dollars. Good luck to them. And for some reason they can buy off lobbyists so they're not subject to the Muhammad Ali Act like promoters are in boxing - just saying."
White responded full blast, in a text message to MMA Junkie that said: "Does anyone give a f*** about Bob Arum or what he thinks? I didn't know he was still alive!!?
