UFC lightweight champion Anthony Pettis was Octagon-side Saturday night at UFC Fight Night 42 to see his brother, Sergio Pettis, score a victory.

The card also featured Benson Henderson, the man Pettis defeated for the title, earn a submission win in the main event over Rustam Khabilov.

After the fight ended, Pettis was “called out” by Nurmagomedov, who posted, “I’m coming for you.” The respond came when “Showtime” mentioned a possible “three-peat” between himself and Henderson. The two also fought over the WEC lightweight scrap, a match won by Pettis.

Pettis, set to defend his title later this year against Gilbert Melendez, didn’t take too kindly to the remarks. He is also scheduled to coach the 20th season of The Ultimate Fighter opposite Melendez, and has been sidelined since winning the belt over Henderson last August.

“Who have you beat again?” Pettis asked Nurmagomedov. “(Everyone) has something to say when I’m injured.”

Nurmagomedov, unbeaten in his MMA career, replied, “I do not touch the disabled, and fight at least once a year if you are a champion.” He is coming off a victory over Rafael dos Anjos this past April.
