Our new Head Coach confirmed that the Irish striker damaged his right ankle in Wednesday night's friendly against Rangers.
Robbie immediately signalled to the bench after Marvin Andrews block-tackled his attempted shot in the 28th minute of our 2-0 defeat at Ibrox. He was stretchered off with a stabilising brace strapped to his right leg.
Jacques, facing the press minutes after the final whistle, said that early indications suggested a ligament problem.
"I've just seen the physio and he thinks it is a ligament problem," said a naturally disappointed Jacques.
"We return to London tonight and will see what the doctors have to say.
"We need Robbie for the first match against Liverpool but now, I'm not so sure."
We'll bring you more details on Robbie's injury as soon as we can...
