The rape happened on Monday Dec. 10, 2018 between midnight and 2am. A couple hours later Kavanagh was distancing himself from Conor saying: "
Well, he would certainly have to convince me to go again"

Then there's all the other rumors. Things like Conor hitting on Kavanagh's GF. Conor's other infidelities (and baby mommas), run-ins with the law, drug use, etc. Hell, these 2 were closer than most coach-fighters are, so Kavanagh is VERY aware of Conor's slide from hungry, hardworking, fighter to the partying, drinking/drugging, starting shit, breaking the law, hooligan with money, he's become.
If John didn't stand to make a shit ton of money off of Conor fights (I question if there will be any in the future) I doubt he would've put up with his antics this long. But beyond Conor, Kavanagh doesn't exactly have a treasure trove of big name fighters. So in the short run he's not going to piss on his winning lottery ticket.
