UFC president Dana White has criticized Usman Nurmagomedov's behavior following an incident at the promotion's event in Shanghai.
As reported by İdman.Biz, Song Yadong knocked out Umar Nurmagomedov, after which his brother Usman entered the octagon and confronted the Chinese fighter.
Some viewers believed that Usman Nurmagomedov attempted to strike Song during the confrontation.
When asked at a press conference whether Usman had crossed the line by entering the octagon, White agreed.
"He definitely crossed the line. I agree with that," the UFC president said.
Usman Nurmagomedov is currently a free agent after his contract with the PFL expired.
The former Bellator lightweight champion has been linked with a possible move to the UFC, where his brother Umar competes in the bantamweight division.
