GIORGOS GIAKOUMAKIS has been ruled out of Sunday's Scottish Cup semi-final.

The Celtic striker won't feature in the clash against Rangers after a hamstring injury.

Giakouamakis limped off in the 7-0 win over St Johnstone last weekend and hasn't recovered from the injury.

Ange Postecoglou confirmed the media this afternoon that Giakoumakis is not fit to play a part at Hampden.

The Celtic boss said: “With Giakoumakis, the prognosis wasn’t anything too serious.

"It will probably keep him out this weekend but we are pretty confident he will be available next weekend.

"David Turnbull trained and is fine, James Forrest trained and is fine as well.”

Celtic will now have to alter their line-up for the semi-final match with Giakouamkis unavailable after an impressive run of form.

Kyogo Furuhashi returned in the rout over St Johnstone, but Postecoglou cast doubt over whether he could play 90 minutes.

Postecoglou added: “I don’t think he is ready to play 90 or 120 (minutes) but he’s ready to play. He was back in and got some match minutes last weekend and he has had two solid weeks of training with the group.

“We train pretty hard and he has matched those levels so that means he is ready to play. Can he see out 90 or 120? Unlikely because he has been out for so long but he is ready to play and that’s the important thing.”

Daizen Maeda and Liel Abada have previously played in a central role up-front for Celtic and could be called upon at Hampden.
