Shane Jennings returned to training last week and it is hoped the Ireland wing forward will be in contention for selection for Saturday's derby.
Nacewa has now accumulated 142 points (including 4 tries) in this year's Magners League. Meanwhile, Jonathan Sexton's 12 point haul on Saturday evening pushed him past the 500 point mark in Leinster colours and 163 points from that tally have come so far this season in 14 games.
Fourth placed Leinster currently lie three points adrift of second-placed Ulster. The team is expected to be named on Friday lunchtime.
