Celtic manager Neil Lennon has revealed that Honduran defender Emilio Izaguirre will be out of action for the next six weeks.
The 26-year-old suffered an injury in the draw with Dundee United at the weekend, but it had been reported that he would return within two weeks.
However, the experienced defender will miss the period leading up to Christmas, beginning with tomorrow's clash with Barcelona at Parkhead.
Meanwhile, James Forrest and Lassad have also been ruled out of the Champions League encounter through injury.
