VIDEO: Anthony Smith Literally Ends Alexander Gustafsson's Career With Submission UFC Stockholm Win

Talk about beating your opponent to a pulp. Anthony Smith dominated Alexander Gustafsson so thoroughly in his win at UFC Stockholm that he actually forced him to retire immediately after the match.

The light heavyweight fight ended in the fourth round as Smith forced Gustafsson to submit.

In the immediate aftermath, Gustafsson spoke to the media, saying "The show is over," before leaving his gloves inside the octagon.

The Swedish MMA fighter entered the matchup with an 18-5-0 record, well short of the 31-14-0 record of his opponent in Smith. Should the 32-year-old call it quits, he'd finish having won two-thirds of his fights.

What a wild ending.
