Assistant coach Richie Murphy said: "Everyone came through the Northampton game unscathed. Kevin McLaughlin, Devin Toner, Gordon D'Arcy, Luke Fitzgerald and Fergus McFadden are all back available and could come in this weekend."
But Murphy confirmed that Ireland prop Michael Bent is currently nursing a neck injury, adding: "Michael took a knock in training. The only information we have is that he has a nerve problem and don't know how long he'll be out for."
Another of the province's internationals, Eoin Reddan, made his first start since March when coming on as a replacement against Northampton and his next appearance will be his 80th in Leinster colours.
Meanwhile, Sean Cronin and David Kearney both came through their first run-outs of the campaign last weekend.
It is likely that a number of younger players will again have the chance to impress in the league opener in Llanelli, with the team set to be announced on Thursday afternoon.
