A heavyweight matchup is the latest addition to the UFC’s first event of 2020.

Aleksei Oleinik (57-12-1 MMA, 6-4 UFC) will take on Maurice Greene (8-3 MMA, 3-1 UFC) at UFC 246, a person with knowledge of the booking told MMA Junkie. The person requested anonymity since the UFC has yet to make an announcement.

Oleinik has dropped his past two in a row, suffering knockout losses at the hands of Alistair Overeem and, most recently, Walt Harris at UFC on ESPN 4 in July. With more than 70 pro fights on his resume, the Russian veteran will look to avoid a three-fight losing skid when he takes on “Ultimate Fighter” alum Greene.

Greene, who started off his UFC tenure at 3-0, recently saw his winning streak come to a halt when he lost by first-round TKO to Sergei Pavlovich in October.

UFC 246 doesn’t have an announced location yet, but is expected to take place at T-Mobile Arena in Las Vegas. The main card airs on pay-per-view following prelims expected for ESPN and early prelims on ESPN+/UFC Fight Pass.

With the addition, the UFC 246 lineup now includes:

Maycee Barber vs. Roxanne Modafferi Drew Dober vs. Nasrat Haqparast Grant Dawson vs. Chas Skelly Maurice Greene vs. Aleksei Oleinik
