The South Korean, already on a booking, challenged Nicky Cleșcenco and sparked panic in the commentary box when Beaton initially looked ready to produce a card.

But no foul was given and Yang escaped what could have been a costly second yellow.

The incident, also highlighted on the BBC's live feed, had Donnelly fearing the worst for the returning winger, who had been booked for a crude challenge earlier in the half.

Speaking on Celtic TV, Donnelly said: "I thought John Beaton was going to his pocket. I don't think it was a foul, though. I think the lad just fell.

"It's a weird one. John Beaton went to go to his pocket, no sooner had he done it and he changed his mind."

Yang was ultimately able to breathe a sigh of relief as Beaton waved play on and kept his cards in his pocket.
