Celtic defender Glenn Loovens cannot understand why he has been referred to the Scottish Football Association's review panel following an incident with Rangers midfielder Maurice Edu.

The Dutchman's studs caught Edu on the back of his knee as his foot came down after making a clearance during Celtic's 1-0 defeat at Ibrox on May 9. The American needed treatment but came back on to continue taking part in the game.

"I'm a hard player but also fair," the former Cardiff defender said. "I just went in for the ball and at some point my leg had to come down to land on the ground. There's no way I tried to hurt the player and I did not try to catch him deliberately."

He added: "Edu went off for treatment and I spoke to him as soon as he came back on. I said sorry, asked if he was okay and he told me he was fine.

"I really don't know what all the fuss is about. It will be looked into but I'd be surprised if any action was taken against me."

The review panel will also look into Scott McDonald's challenge on Dundee United defender Lee Wilkie during Celtic's 2-1 victory on Wednesday.

The review panel is set to make a ruling early next week but Loovens expects to be cleared.
