O'Hara is stepping up his recovery from a troublesome groin injury which has seen him out of competitive action since March.
Manager Stale Solbakken will include a number of first team players including Georg Margreitter in the match at the club's training ground.
"We're playing a behind closed doors game tomorrow against Wigan and Jamie is playing 45 minutes," said Solbakken.
"Georg Margreitter is also playing, 75 or 90 minutes and he's been back in training for a while.
"More or less all of the fit players who didn't play at the weekend will have 45 or 90 minutes tomorrow, depending on how much they have played.
"It's important some of them get their match practice with this busy period coming up so they're ready because we will use more players than ever over the Christmas period."
