Pete Mahon's former club, UCD, are the visitors to Richmond Park for tonight's Airtricity League match.
The Saints will be looking to bounce back from last week's defeat against the League leaders, Sligo Rovers.
It's not just the Saints' manager who is up against his former Club - David McMillan, Evan McMillan, Shane McFaul, Ian Bermingham, Derek Doyle and Brian Shortal have all previously played for UCD.
Conor Kenna misses out again with a knee injury, but Pete Mahon has no other injury concerns or suspensions.
