Frankie Edgar put a likely end to B.J. Penn’s mixed martial arts career with a brutal TKO victory in the third round of the Ultimate Fighter 19 Finale on Sunday in Las Vegas.

Edgar (16-4-1) defeated Penn (16-10-2) for the third time in his career with a one-sided performance that left Penn bloodied in the middle of the cage as referee Herb Dean stepped in to end it at 4 minutes, 16 seconds.

Penn was fighting at 145 pounds for the first time but got beat up severely for the third straight fight. At 35 years old, his 13-year MMA career is likely over after losing for the fifth time in his last seven fights.

“Frankie did a great job,” Penn said. “I shouldn’t have came back.”

Penn is one of two UFC fighters to hold world titles in multiple weight classes.
