O'Halloran damaged his knee during the warm-up for Saturday's 1-0 home win over Oldham and was forced out of the action after 20 minutes, with David Amoo introduced in his place.
Ian Goodison similarly suffered a knock beforehand but the 40-year-old centre-back is set to retain his place at the Banks' Stadium having completed 90 minutes at the weekend.
Stoke loanee Mamady Sidibe is expected to fall foul of hamstring trouble once more, although Rovers boss Ronnie Moore has refused to rule the experienced striker out of contention.
"We've got to wait on Mamady," he told the club's official website. It was just a bit tight on Friday so Saturday was a bit early for him.
"We're hopeful he'll get through the training session (on Monday) and possibly play but I'd say it's 60-40 he won't play."
Winger Adam McGurk (collapsed lung) remains sidelined along with midfield duo Andy Robinson (hamstring) and James Wallace (knee).
