In a column for The 42, Kavanagh talks about the fight preparations and says that McGregor will fight under boxing rules at 145 pounds.
That fight is close to being agreed and it will be at a weight very close to 145 pounds — maybe just a couple of pounds above that — so Conor will show once again that making that weight, if necessary, isn’t an issue for him. Everything has been agreed from Conor’s perspective, from numbers to ruleset (pure boxing). I don’t know what’s taking Mayweather so long to sign the contract but we’re 100% ready to go. The ball is in his court now. We’re training for the fight — September has been mentioned — so we’re just waiting for the news with each passing day. The experts may not be giving Conor much of a chance, but I wouldn’t allow myself to be involved in preparing any fighter for a contest if I didn’t think we could win. I know a lot of people are dismissing it as merely a money-grab or a spectacle. If it purely was that, I’d wish Conor well but I wouldn’t be part of it…I believe he can do it and Conor is 100% sure about that outcome.
