Jon Jones has heavyweight punching power.

Don’t believe me, just ask Alexander Gustafsson.

The two collided this past weekend, with Jones earning a decision victory and successfully defending his UFC light heavyweight title.

In the fourth round of their bout, “Bones” connected on one of his vicious elbows, and left “The Mauler” feeling it.

“I saw stars,” said Gustafsson, during an interview on UFC Tonight. “It was a good shot. I wasn’t out, I was still in control.

“I just kept trying to move.”

Gustafsson also put to rest any rumors that he has already been offered an immediate rematch, saying “No, it’s just rumors now.”
