Johnny Sexton is in line for his season's bow in Leinster's trip to Ulster on Friday night.
The 37-year-old is in the selection mix after having to bide his time over the first two weeks of the URC season.
And he could make an instant reunion with his Ireland half-back partner Jamison Gibson-Park, who was due to play in last Friday's home victory over Benetton before sickness ruled him out.
