Ireland trio Brian O'Driscoll, Gordon D'Arcy and Girvan Dempsey could return to Leinster's starting line-up this weekend.
The run-away Celtic League leaders travel to Llanelli Scarlets on Saturday and coach Michael Cheika hopes to have the three influential backs available.
Ireland skipper O’Driscoll is recovering from a hamstring tear he suffered in Ireland’s 16-12 RBS 6 Nations defeat to Wales, while fellow centre D’Arcy broke his arm in the opening 16-11 victory over Italy.
Full-back Dempsey has been struggling with a hip injury which forced him out of Ireland’s last three championship matches.
All three missed Friday’s 34-18 victory against Glasgow Warriors which saw Leinster move 10 points clear at the top of the table.
