Roy Jones Jr. wants in on the Mayweather/McGregor cross-promotion machine, calls out Anderson Silva; fans call for Roy to retire.

Boxing legend Roy Jones Jr. is far removed from his physical prime, but his business mind is still sharp. Roy figures, if Floyd Mayweather and Conor McGregor can grab daily headlines pushing a cross-sport fight, he might as well throw his hat in the ring. So he called out UFC legend Anderson Silva to fight on the undercard.

Silva and Jones combined are almost 90 years old, which would probably set records if the two end up sharing a ring. The money a Mayweather and McGregor fight card would generate is a genius retirement plan.

Predictably, not all fans are onboard. Jones, 48, is a shell of his former self and has spent the past 13 years tarnishing his in-ring legacy.

Jones is 16-8 and has been stopped five times since 2004. He was 49-1 before then, his only loss coming via disqualification for hitting Montell Griffin after he’d already floored him.

Fans and friends have been begging Jones to retire for years, to no avail. He knocked out Bobby Gunn at the Chase Center in Wilmington, DE last weekend, so he’ll likely fight on.
