CELTIC defender Christopher Jullien faces an extended spell on the sidelines after picking up a knee injury against Dundee United on Wednesday.

The knock meant the Frenchman was ruled out of Saturday's Old Firm derby, with Parkhead boss Neil Lennon revealing before the game at Ibrox that the 27-year-old is expected to be out for the next three or four months.

He told Sky Sports: "He’s very important player but it’s a bad injury.

"We are going to lose him for quite a period of time.

"It will be maybe three or four months so it’s a hammer blow for us."
