But they come against an inform Connacht side who remain unbeaten in this years Celtic competition.
For the Irish to stop the Valley Commandos, Connacht coach Steph Nel will have to come up with a plan to nullify a Ponty pack that has been dominant all season.
The front eight have picked up the form that saw five travel to South Africa in the summer, and with English prop Duncan Bell playing well, the Pontypridd pack look awesome.

NEATH V MUNSTER (5:30)
This clash makes the mouth water. Last year's Celtic League finalists versus the team many people tip for the title.
Munster are 13-8 favourites to win the title, but Neath need a big performance ahead of next weekend's Heineken Cup opener against Leicester- and they'll prove a hard nut to crack in front of the home fans.
Neath coach Lyn Jones has added defensive steel to the Welsh side's arsenal this season, and it will take an imaginative Munster side to penetrate the All Blacks back line.
With two world class kickers on show- Neath's Lee Jarvis and Munster maestro Ronan O'Gara, any errors will be punished. This match will be close, and tight, and could come down to the pair's goal kicking talents.
The winner will virtually be guaranteed a home quarter final, and an easier route to the final.
