Conor McGregor Would Thrive In Bare Knuckle Fighting, Says BKFC Star

CAN'T STOP, WON'T STOP

If Conor McGregor would ever throw down in a ring without gloves ... BKFC star Houston Alexander tells TMZ Sports the dude would be a problem!!!

Alexander -- a former UFC and Bellator fighter who's been brawling professionally without mitts since 2021 -- says Conor is so skilled with his hands ... he thinks there'd be no issues for The Notorious if he chose to eventually go from the UFC to the BKFC.

Of course, the topic came up because Conor sure appeared to be interested in making the switch after watching Mike Perry's BKFC fight against Luke Rockhold back on April 30.

You'll recall, McGregor stepped into the ring following the tilt ... and he seemed to be down to fight…
