Heading into his fight against Floyd Mayweather, Conor McGregor is the biggest underdog since Sylvester Stallone entered the ring against Apollo Creed.
Ahead of the fight, Stallone re-posted a video mashup of McGregor and Mayweather as Rocky and Clubber Lang from Rocky III. The clip is of Rocky McGregor knocking out Clubber Mayweather, which is probably the only version of this fight where that actually happens.
If McGregor does pull this off, it will be a Rocky level upset. It would appear Stallone is pulling for the Irishman.
