Clontarf are waiting for the all-clear for second row Ben Gissing (hip) and out-half Dave Hewitt (neck) before selecting their side for the All-Ireland league final against Ballymena at Lansdowne Road on Saturday.
Meanwhile, Ballymena centre Huw Jones is 50/50 to be in the starting line-out.
However, if he cannot make it, Scott Young will shift to centre and Andrew Maxwell will be promoted to the left wing.
There is still some question over whether Peter Spence or Andy Munson will be at scrum-half.
