British and Irish Lions and Leinster flanker Sean O'Brien is in the frame to feature for the first time this season when they face Munster on Saturday.
O'Brien, who has not played since the successful tour of Australia, is set to be in the Leinster squad that travels to Limerick for their PRO12 match.
Leinster revealed the news in an injury update that included the possibility of former Australia winger Lote Tuqiri being involved this week.
"Aside from the usual bumps and bruises the medical team have reported no major injury concerns arising from Friday night's bonus point victory over the Cardiff Blues. Ireland quartet Gordon D'Arcy, Mike McCarthy, Kevin McLaughlin and Eoin Reddan are all expected to return to the panel," Leinster explained in Monday's statement.
"McLaughlin and Fergus McFadden - who successfully came through his first outing in the RDS this season - both now lie three appearances short of the 100-cap mark for their home province.
"Cian Healy, Jamie Heaslip, Rob Kearney and Brian O'Driscoll all came through their first starts of the campaign, while Sean O'Brien is in the frame for the first time this season ahead of the trip to Limerick. Dominic Ryan's next appearance will be his 50th in Leinster colours."
