Smith and Clark were elevated to the main event after Curtis Blaydes was pulled from his heavyweight showdown with Derrick Lewis after testing positive for COVID-19. Smith and Clark immediately agreed to a five-round fight but Smith made sure that all 25 minutes weren't needed. 

After absorbing an overhand right from Clark, Smith immediately dragged the fight to the canvas and cinched in a triangle choke to earn the submission at the 2:34 mark of the opening frame. 

Smith snapped a two-fight losing streak and pushed back on the notion that he should retire with an impressive performance against a heavy-handed opponent who sought to pick up the biggest win of his career with a highlight-reel finish.

Smith used a bodylock to take Clark down after tasting some of his opponent's power. With a distinct advantage on the ground, Smith manuevered into position as he snaked his legs into a triangle choke. Clark had nowhere to go and was forced to submit. 

Smith improved to 34-16 overall with his latest finish. The 32-year-old also entered the win column for the first time in 2020. Clark fell to 12-5 and saw his two-fight winning streak end.
