The UFC was back in its Las Vegas Apex facility on Saturday night with the UFC Fight Night 239 card. It wasn't exactly star-studded, but it provided some fun viewing for fans who decided to tune in, and it opened the door to some exciting matchups in some of the promotion's most popular divisions.
The main event was contested at heavyweight, where No. 9 contender Tai Tuivasa looked to defend his spot against the 10th-ranked Marcin Tybura.
After three straight losses, Tuivasa was in desperate need of a win, but Tybura had other plans and locked up a submission in Round 1.
