Michael Mifsud is an early doubt for Saturday's clash against Bristol City after returning from international duty early.
The City striker picked up an injury after taking a knock during Malta's 2-2 draw against Turkey on Saturday and won't be risked for their friendly against Armenia tomorrow night.
Instead, the 26-year-old will return to Coventry for treatment.
Said Malta national coach Dusan Fitzel: "He took a knock in the first-half and then gave away five to six balls. I was contemplating taking him off but I waited until half-time. He received more treatment from the doctor and he was better in the second half.
"Michael would have been available for the friendly but I decided not to risk him. The Coventry coach (Iain Dowie) initially asked for Michael to be released from the friendly but I told him that my plan was to play him for 45 minutes.
"However, there's no point in calling on Mifsud if he's not fully fit. It's better if he continues to receive treatment in the hope that he will be fit to play for Coventry on Saturday.
"We need Michael to be fit and playing more regularly for his club because that would also benefit the national team."
