UAE giants Al Ahli are sweating on the fitness of striker Asamoah Gyan who suffered an injury in Sunday's Emirati-Moroccan Super Cup.
Gyan scored just two minutes into the match Rashid Stadium and the won the trophy for the Dubai-based side.
UAE midfielder Habib Fardan flicked a loose ball for Gyan, who applied a first-time finish inside the penalty box to make it five goals in six matches.
But the Shanghai SIPG loanee was stretchered off just afterwards with a muscle problem.
Gyan will be observed ahead of the weekend's league match against Dibba Al Fujairah.
