Jamie Ward could miss Derby's game with Southampton after pulling out of the Northern Ireland squad with a hamstring problem.
The attacker came off towards the end of the 4-0 defeat to Leicester on Saturday with the injury, and he has withdrawn from the Northern Ireland squad for their forthcoming games with Estonia and Italy.
The 25-year-old will now remain in the East Midlands in a bid to be fit for the Rams' game with the npower Championship leaders on October 15.
Ward earned his first Northern Ireland cap in August and has played in all of Derby's league games so far.
