Never before had three UFC titles changed hands in one night, but never before have we seen a card play out quite like UFC 217.

In a night of thunderous upsets, Rose Namajunas slept Joanna Jedrzejczyk inside a round, T.J. Dillashaw put the Team Alpha Male rivalry to rest with a second-round knockout of Cody Garbrandt, and one of the greatest fighters of all-time — Georges St-Pierre — added another legendary chapter to his legacy with a title-winning, third-round submission over Michael Bisping. Altogether, it was an unbelievable night of fights, and as always, the pros loved it every step of the way.

Check out reaction to the championship action below, plus the best of the rest from a wild night at UFC 217.
