You don't often see heavyweights employing high-flying moves, but former UFC heavy Alex Nicholson (12-5) clocked Jake Heun (11-7) with a flying-knee TKO 58 seconds into Round 2 to kick off the main card of the inaugural event of the Professional Fighters League, a rebranded World Series of Fighting, on Thursday night at the Hulu Theater at Madison Square Garden in New York. "I'm a real-life gladiator," said Nicholson.
