The second half of the PFL season begins tonight with PFL 4 2021, where lightweights and featherweights will take center stage once again. The event is headlined by a non-league lightweight showcase bout between 2016 Olympic boxing gold medalist and undefeated professional boxing champion Claressa Shields, who is making her MMA debut, and the 3-6 MMA veteran Brittney Elkin. Elkin is looking for a better outcome against her second highly-touted Olympic gold medalist after losing by first-round submission in former judo great Kayla Harrison‘s MMA debut in 2018.
At lightweight, Clay Collard, Akhmed Aliev, Alexander Martinez, Marcin Held, and Raush Manfio each have three points, all having earned decision victories at PFL 1 2021.
