Never known as an aggressor in the boxing ring, Floyd Mayweather's reputation as the most gifted defensive and evasive fighter in the sport's history will be front and center once again on Saturday.
In the other corner, Conor McGregor all but epitomizes everything Mayweather is not - a ruthless attacker with a flair for the dramatic, having built that notoriety fighting in the UFC.
"Money" enters the bout with a perfect 49-0 record, though he hasn't won by knockout since 2011. McGregor, meanwhile, has accumulated a 21-3 record as a mixed martial artist with his latest win coming in 2016 in the form of a KO/TKO against Eddie Alvarez.
With "The Money Belt" on the line, how will Saturday's highly anticipated bout be decided? It's your call.
