The first leg of the Professional Fighters League’s regular season comes to an end with PFL 3 on Friday at Esports Stadium Arlington in Arlington, Texas, and does so featuring a card complete with plenty of star power at the top of the bill. After a brief period as perhaps the sport’s most coveted free agent, Kayla Harrison returns to PFL in hopes of a threepeat as women’s lightweight champion. The two-time Olympic gold medalist will square off against Marina Mokhnatkina in the main event. Thus far, Harrison’s opponents have been little more than props in the cage as the American Top Team standout builds her resume.
