Aaron Amadi-Holloway a doubt for Oldham's match with Sheffield United
Oldham could be without striker Aaron Amadi-Holloway for their League One clash with leaders Sheffield United.
The 24-year-old, who has only missed one game since signing for the club in January, was forced off during last weekend's draw against Peterborough with a hamstring strain.
Defender Anthony Gerrard also limped off late on after catching his studs in the turf but is expected to be fit.
Ryan McLaughlin is definitely absent after being called up to the senior Northern Ireland squad and Josh Law could take his place.
Sheffield United will be without defender Daniel Lafferty, who is also on international duty with Northern Ireland.
Lafferty is hoping to win his 14th cap for his country in Sunday's World Cup qualifier against Norway at Windsor Park.
Blades boss Chris Wilder otherwise has a fully-fit squad to choose from as his side bid to extend their six-point lead at the top of the table.
Striker Leon Clarke returned to training last week following an ankle injury and could be in contention for his first appearance since mid-January.
