Sergei Pavlovich vs. Tai Tuivasa Booked for UFC on ESPN 42 in Orlando

A heavyweight showdown between Sergei Pavlovich and Tai Tuivasa will serve as the UFC on ESPN 42 co-main event.

MMAjunkie.com was first to report the booking. UFC on ESPN 42 takes place at the Amway Center in Orlando, Fla., on Dec. 3 and is headlined by a welterweight scrap pitting Stephen Thompson against Kevin Holland.

Pavlovich will take a four-bout winning streak into the matchup with Tuivasa. The 30-year-old Russian debuted in the Octagon with a first-round TKO defeat against Alistair Overeem but has since scored successive finishes against Marcelo Golm, Maurice Greene, Shamil Abdurakhimov and Derrick Lewis. The Eagles MMA representative is 16-1 as a professional overall, with 13 victories coming via KO or TKO.

Tuivasa, meanwhile, had a five-bout winning streak snapped in a third-round technical knockout loss to Ciryl Gane in the UFC Fight Night 209 headliner. The 29-year-old Australian is 8-4 in the Las Vegas-based promotion with notable triumphs against the likes of Lewis, Augusto Sakai, Stefan Struve and Andrei Arlovski, to name a few.
