The visitors travel without James Howitt, while Jy-Mel Coleman faces a late fitness test to determine his availability.
Hemel coach Troy Perkins said: “Last week I was disappointed with our lack of ball control. We completed 40 per cent of our sets, which makes life tough against anyone.
“We’ve got to hold the ball a bit more and put the opposition defence under pressure.”
He added: “Oldham are one of the favourites to win the league so we know this is going to be a tough fixture, but if we can improve on a few areas from last week then we can have a good shot at them. We went up there last year and only got beat late on, so we’ll travel with a bit of belief in us.”
