Chris Sutton appeared to be the target of an X-rated hand gesture from pundit Paul Ince on BT Sport's morning preview show.
The broadcaster apologised on-air for the incident that took place as their Early Kick-Off show headed to an advert.
Record Sport pundit Sutton and the former Manchester United and Liverpool midfielder were involved in some lively debates before Ince's gesture towards the Celtic legend.
The show is adored for the rapport between host Robbie Savage and Sutton - with many fans tuning in just to see the pair go at each other.
But Ince could be set for a spell on the sidelines after his video nasty was spotted by shocked armchair supporters.
The Guv'nor is known for his no-holds barred approach but TV bosses will likely take a dim view of his moment of madness.
Ince and Sutton had been discussing a host of subjects with the pair both agreeing Celtic's level is the Europa League after their shock exit at the hands of Cluj.
