What happened: Ankalaev submitted Bogdan Guskov at 2:41 of Round 5 in the Etihad Arena main event. Ulberg won the vacant light heavyweight belt in April with a first-round knockout.
Why it matters: The victory returned Ankalaev to the title picture after he lost the belt last October. A booking would give Ulberg his first defense against the UFC's No. 1-ranked contender.
By the numbers: Ankalaev is 22-2-1 and Ulberg is 15-1, giving the potential matchup a combined record of 37-3-1.
What to watch: UFC's choice for Ulberg's first title defense is the next development to watch.
