As the clock ticks down to Saturday's fight between Conor McGregor and Nate Diaz, the Dubliner took part in the customary open workout last night.

In front of a crowd of fans and media in Las Vegaws, McGregor went through a light workout with a sparring partner as he tunes up for the challenge Diaz will pose.
