Aberavon themselves occupy an unaccustomed eleventh position in the table having won one and drawn one of their nine games played.
Ponty's list of injury absentees include winger Owen Jenkins (ankle), outside half Simon Humberstone (groin), scrum-half Gareth James (hamstring), hooker Jack Dando (shoulder), prop Pat Palmer (shoulder) and second row Craig Locke (ankle).
Making a comeback from a broken hand is centre Gavin Dacey who takes a place amongst the replacements alongside brother Kristian, the hooker drafted in from the Blues senior squad.
Promising young scrum-half Joel Raikes will make a first start for Ponty on permit from Ynysybwl whilst another Blues Academy member, prop Bradley Thyer from Beddau covers on the bench.
Pontypridd team manager Richard Langmead is hopeful that the recent break from action will not deter his squad from going all out for a crucial win at the Talbot Athletic Ground.
"We have tried to keep the boys fresh, introducing new training routines which have been enjoyable" said Langmead.
"We have trained well in the week and must now carry that momentum into the match itself.
"A visit to Aberavon is always a hard task, they are a strong unit who have power up front and plenty of guile amongst the backs.
Their league position is a false one and they will again prove to be formidable opponents, especially on their own patch where we rarely manage to get a result.
"We will approach the game in positive mood, refreshed, and determined to gain a win to keep in touch at the top of the Premiership."
