Third-placed 'Quins will be without free-scoring fly-half Ian Humphreys however, for their trip south to Cork Con.
The scorer of 38 points in his last two outings for 'Quins, Humphreys suffered a shoulder injury in DC Gillespie's side's Ulster Cup final loss to Ballymena last week.
But even without him, Gillespie - hoping to steer the Deramore men to their second success AIL semi-final - feels 'Quins should have enough for tomorrow's test.
"We are capable of doing it but the injuries have certainly knocked the cohesion and continuity out of us," said Gillespie, who is also without winger Mark Kettyle and pack powerhouse Colin Atkinson.
"It's always tough going to Munster as Con are competitive and they got a good win at Trinity last week. They have a big squad but we're certainly up for the challenge."
Champions Shannon - semi-final conquerors of 'Quins last year - can guarantee a home date for next month's play-offs at off-the-boil Buccaneers.
Out of the title race, Buccs have little to play for but with Shannon visiting the Ballinasloe venue of Moher Road for the first time and David Kelly set for his first start, possibly in the second row, since January, the Pirates could fire.
Former Ireland scrum-half Stephen McIvor will watch his Blackrock College charges go through their paces at Stradbrook for a final time.
Departing 'Rock after two seasons, McIvor is keen to bow out on a winning note at home to Galwegians.
Elsewhere, with Dungannon's derby clash with play-off chasers Ballymena postponed until Wednesday due to the death of a 'Gannon club official, County Carlow's trip to Trinity takes on added impetus.
Second-from-bottom Carlow could leap a point ahead of Trinity with a bonus point win and will be again reliant on veteran fly-half Richie Murphy to kick them to victory.
The midlanders boss Ray Ward is a little worried though, having previously coached the Trinity Under-20s.
"They definitely have the ball skills and if they decide to throw it around, we could find ourselves conceding defence," said Ward, whose side have racked up just one away win throughout the campaign.
At Castle Avenue, bottom side Lansdowne could be relegated if Carlow win - and Andy Doyle's men fail to pick up anything against Clontarf.
Meanwhile, with former leaders UCD nine points behind fourth spot and disappointingly out of title contention, there's only pride on the line for the students against play-off-bound Garryowen at Belfield.
