Trent McClenahan could miss several games for Hereford United as he has been called up into Australian Olympic squad.
"Trent has been picked for a game in Iran, so we might lose him next week," manager Graham Turner told BBC Hereford and Worcester.
"He might miss several more games between now and the end of the season having been selected for that squad."
Meanwhile, in his weekly interview with the station, Graham Turner has also spoken of the change in formation used in the last few games.
"The players took it all on board - they adapted very well to it.
"Sometimes during the course of a season, things like that can present a fresh challenge to players.
"But they're refreshed by the change of systems and they look as though they are enjoying the new approach."
Finally on-loan Bulls striker Stuart Fleetwood scored twice for Accrington in a reserve game against Wrexham last evening.
