Don Robertson was lenient with John Lundstram but another ref may well have sent the Rangers star for an early bath after his meaty challenge on Kyogo.
That's the view of former top whistler Steve Conroy who feels Robertson took a 'high risk' approach to officiating the derby at Hampden. Lundstram's tackle on the Celtic star set the tone of battle in the chaotic cauldron of Scottish Cup semi-final battle but referee Robertson opted to take no further action as he got to grips with the clash after being thrown into the Hampden clash when Willie Collum pulled up injured pre-match.
Replays afterwards have shown Lundstram was high but VAR didn't intervene as the game finished 11 vs 11 with Celtic going on to win through Jota's header. But on Lundstram's challenge, Conroy told NewSlotsKosh: “The only challenge of substance was the John Lundstram one (on Kyogo). I think it merited a yellow so it was a high-risk strategy by Don but it worked for him and I suspect if it had been another referee in his place it might have been a red.
