Despite missing out on a return fight with arch-rival, Michael Chandler for the time being at least — it appears UFC star, Conor McGregor is ramping up his training preparation ahead of an eventual Octagon return, in the form of some heavy boxing sparring.
McGregor, a former undisputed lightweight and featherweight titleholder under the banner of the organization, missed out on a fight with Chandler — albeit for the time being earlier this week, with the Missouri veteran giving up on a failed pairing to book his own year-end return.

Sidelined since a submission loss to common-foe, Dustin Poirier two years ago, former Bellator MMA lightweight kingpin, Chandler has booked a five round rematch with former lightweight champion, Charles Oliveira in the co-main event of UFC 309 in November, returning to Madison Square Garden.
