After taking maximum points off Port Vale at Loftus Road and continuing their unbeaten home record, the R's will be looking for another three points to keep the heat on leaders Plymouth and Bristol City.
Rangers are sitting in 3rd place, three points of second placed Bristol but a game in ahead and a superior goal-difference means everything is possible in the race for automatic promotion in the coming weeks.
It will be an interesting encounter considering the Latics beat Rangers earlier in the season at Boundary Park after receieving the news that there then manager Ian Dowie had walked out.
It's been a tough ride for Oldham after their playoff deafeat to Rangers last season. Money problems, manager walk-out, players revolt...they've dealt with the lot but their a determined, hard-working sside who don't lack quality and it will be a hussle bussle encounter down in West London tomorrow.
Rangers have no new injury worries and are expected to line-up the same as on Tuesday evening despite Jamie Cureton coming off the bench to net twice.
Oldham are lying in 18th spot and have only won once away from home but are sure to raise their game against the R's and Scott Vernon spearheading the attack with 13 goals this season needs to be watched. 1 win in there last 6 is not an attractive run of form but neither is Rangers current stats so it will be a fiery feast down at Loftus Road tomorrow.
