Martyn Waghorn has revealed his devastation at being ruled out of the Old Firm derby.

Rangers’ top scorer has been sidelined for the last two months with a knee injury but had hoped he could make an unexpected return to face Celtic in the mouthwatering Scottish Cup semi-final on Sunday.

Waghorn, who has scored 28 goals in 34 matches for Rangers this season and also weighed in with eight assists, picked up the injury in a fifth-round win against Kilmarnock in February.

Mark Warburton insisted last weekend that the former Wigan and Leicester forward was not in contention to play and Waghorn has now accepted defeat in his bid to hoping to convince the manager to have a change of heart.

“Gutted to be missing the old firm Sunday, just too soon! still can’t wait for the game,” wrote Waghorn on his personal Twitter account.

Celtic, who are closing in on a fifth concsecutive Scottish Premiership title, are the favourites to win the cup clash as they target the Scottish double.
