Two of the top stars in the Professional Fighters League roster will compete at the upcoming Fight Night charity event in Washington, D.C., on Nov. 2, the promotion announced Thursday.

Ivanov, a former heavyweight champion under the WSOF banner, will take on Caio Alencar, who finished Jared Rosholt in 77 seconds in his only appearance inside the WSOF cage.

Lance Palmer, a two-time WSOF featherweight champion, is also set to compete at the event with a yet-to-be-announced opponent. The fight card will be streamed live on PFL’s website.

PFL has partnered with Fight For Children for this event. FFC is a non-profit organization with a mission to ensure all kids in the District of Columbia region, especially those in the highest need areas, receive a quality early education and solid foundation for future success.

“Fight Night has been a staple in Washington for nearly three decades, and the Professional Fighters League is excited and honored to have some of our top athletes compete at this year’s event,” PFL Executive Chairman Russ Ramsey stated in a release.

“MMA fighters are among the most disciplined, driven, and committed athletes in the world – traits we hope to instill in our own kids and children everywhere, regardless of their backgrounds. As a D.C.-native myself, I have seen the incredible work of Fight For Children up close, and can think of no better way to cap off 2017 and begin the PFL’s mission of putting athletes first and reimagining the sport of MMA forever.”
