Conor McGregor continues to be the ultimate troll online. While sliding in digs at Floyd Mayweather and his other opponents through his Twitter account, the current 155-pound UFC champion released a boxing training video on his Instagram page on Wednesday.

It's not the first time we've seen McGregor suit up for boxing as a part of his training, but of course, timing is everything with the 155-pound champion. If this is something more than just a tease at boxing, let's hope he keeps his hands up a little bit more.
