He stayed on his feet but his legs had gone and his arms must have felt like lead.
Hard concussive, accurate punches rain in from Mayweather who is hurting McGregor who stumbles across the ring and into the ropes from a right hand, off balance, and is close to going down.
The attack continues. Left. Right. Left. McGregor’s head is torqued across his shoulders. This is nasty dominance now and Mayweather looks the great boxer and McGregor the MMA fighter.
Brilliant, valiant effort by McGregor. After two lefts on the ropes, referee Robert Byrd has seen enough, protects McG and waves it off.
