Rónan Kelleher and Ryan Baird are available for Leinster's Heineken Champions Cup quarter-final clash with Leicester Tigers at Welford Road on Saturday (5.30pm).
The duo's return to fitness is a big boost ahead of the encounter with the Premiership leaders.
Baird has recovered from a back injury picked up during the Six Nations while Kelleher was a late withdrawal from the squad against Cell C Sharks with a shoulder knock.
Kelleher returned home early from South Africa in a bid to be right for Saturday's vital fixture.
The remainder of the squad who played two URC games there has now returned, along with head coach Leo Cullen, with first place in the URC table guaranteed on the back of two losing bonus points.
Leinster's frontliners worked away at the province's UCD base while their colleagues were in South Africa, so Cullen will hope to hit the ground running with preparations early in the week.
Max Deegan, who has a shoulder issue, will be further assessed this week before a final decision is made on his availability, but hooker James Tracy is ruled out with a neck injury.
