Leinster Coach Michael Cheika commented: "I am delighted that David was so keen to return to Leinster to provide cover over the next few weeks. David has outstanding experience as an international class operator and I know how highly he is regarded by those who played with him during his last spell with Leinster, which makes me very confident in him playing an important role for us at this important stage of the season. The fact that the he has already worn the blue jersey and understands our culture is a real bonus.
"With Felipe Contepomi and Isa Nacewa due to return to action over the next few weeks, it is important that we maintain our momentum and David will provide the extra cover we need in the out-half position behind Jonathan Sexton."
