"Shefki's injury is a blow to us, he scored with a great header but he's got a puncture wound on the inside of his thigh and will probably be out for a couple of weeks." the former Northern Ireland international told the Official Club Website.
"We knew before the game that this was going to be pretty difficult but getting off to a good start was exactly what we hoped for but we lacked a bit of composure and didn't really get the ball down and play which was disappointing for us.
"We've got to be better than that, we simply did not play well. Kelvin made some great saves, particularly in the first-half and that kept us in it.
"Yet again our back four were really good and our 'keeper was outstanding. We're still winning games and that is the positive you take away from today."
