'Really, really poor' - Sky Sports pundits hit out at Brighton loanee for Saturday horror challenge

The Brighton loanee has struggled for form in Scotland, and started the Glaswegian derby on the bench, with Hoops manager Neil Lennon opting to give Nir Bitton the nod at the heart of defence alongside Kristoffer Ajer.

Duffy was introduced into the action shortly after the hour mark, but picked up a yellow card just 10 minutes later for a late, lunging challenge on Gers winger Ryan Kent.

And the common consensus among Sky’s panel of pundits after the match was that he should have been shown a straight red for the tackle.

Former Celtic midfielder Stilyan Petrov said: “It’s a really poor challenge.

“It’s frustration. He’s coming on, they’re losing the game, he’s trying to get back in the game.

"Actually, I think he’s very lucky not to get a red card. I think it’s a really really poor challenge.”

Ex-Rangers hitman Kris Boyd agreed, adding: “I think he’s also wrapped his leg around as well.

"If you see, the other leg comes round as well to make sure that he wipes him out.”

Former Everton and Scotland talent James McFadden rounded out the unanimity, saying: “That’s the one where you’re running the risk.

"It’s alright having a professional foul, which I think is what he’s trying to do – I don’t think he’s intending to hurt – but when you bring that left leg round as well it looks so much worse.

"I think he’s very fortunate to get away with that one.”
