Manny Pacquiao is widely regarded as one of the greatest boxers to ever step foot in the ring, last competing in a losing effort to Jeff Horn this past July.
UFC Lightweight Champion Conor McGregor made his professional boxing debut this past August, losing via tenth round TKO to Floyd Mayweather.
While neither competitor has announced any future plans, the boxing great has teased the possibility of a boxing fight against McGregor.
Pacquiao did so via a post on Instagram:
McGregor is expected to return to the Octagon for his next fight, with his coaches saying that UFC Interim Lightweight Champion Tony Ferguson being the logical opponent.
Horn and Pacquiao were expected to meet again on November 12, but Pacquiao pulled out of the proposed bout before it even became official.
The UFC Lightweight Champion has yet to respond to the post from Pacquiao.
