Last night, in the co-main event of UFC on Fox 26, Team Alpha Male prospect Josh Emmett stepped into the Octagon for a short notice bout with long-time featherweight contender Ricardo Lamas. Though Emmett unfortunately missed weight for this fight, he managed to make good on the opportunity in the end, knocking Lamas out with a swooping left hook in the first round.

Unsurprisingly, this massive upset win generated some interesting reactions from Emmett’s fellow pros on Twitter. See some of the best reactions below!

The secret of success is being ready when your opportunity comes! Congrats @joshemmett155 @teamalphamalemma
