John Cooney is expected to be benched again when Andy Farrell names his side today to meet Wales in Dublin for Saturday's round two of the Six Nations.
Though Cooney impressed after coming on for Conor Murray with 20 minutes to go in last weekend's 19-12 win over Scotland, he may not have done enough to break up the established half-back partnership with Johnny Sexton.
However, in an unusual move, both scrum-halves appeared together for media duties in Dublin with their on-field rivalry again being the main talking point.
Farrell is set to make minimal changes, with centre Robbie Henshaw likely to come in for sidelined Garry Ringrose. Flanker Peter O'Mahony may also start. Ulster's Will Addison could be benched.
