Martin O`Neill`s worst fears were realised today when Jackie McNamara was ruled out of the Champions League clash against Lyon.
The good news that the versatile Scotland international had not suffered a dislocated shoulder were quickly tempered by fears that he had still sustained significant ligament damage.
He was rushed to hospital after colliding with Fernando Pasquinelli in the latter stages of the 2-0 win over Livingston.
An X-ray has since revealed that he has not broken anything but it would appear that there is significant ligament damage.
McNamara has now joined the suspended Alan Thompson and the injured Didier Agathe on the sidelines and is facing a lengthy lay-off.
Bobo Balde also sustained a back problem against Livingston and O'Neill has revealed that the defender will be monitored closely with the hope he will be fit enough to take his place against the French champions on Wednesday.
"Bobo still has a sore back but he is improving and we'll keep a close eye on him over the next day or two," he said.
