Good thing for Frank Mir and Herb Dean.

The UFC legend and the highly regarded referee had to pull apart a pair of fighters who nearly threw down at ACB 87 weigh-ins Friday in England.

Robert Whiteford confronted Kane Mousah before he even stepped on the stage. Then, the two went eye-to-eye during a faceoff, but the brim of Mousah’s hat hit Whiteford in the nose. Whiteford slapped the hat off Mousah and then shoved his face.

Before things could get totally out of hand, Mir grabbed Whiteford from behind and Dean pulled Mousah away. Mir is the ACB color commentator and Dean is working the event Saturday as an official.

Whiteford, a UFC veteran, and Mousah will meet in the featherweight main event of the card from Nottingham. Whiteford (14-4) has won two straight since being cut from the UFC, while Mousah (10-1) has won three in a row.
