Mulhern joined the Robins from Leeds Rhinos for the 2016 season and established himself as a reliable prop forward during his first year with the club.
Standing at 6ft 3in and weighing over 17 stone, the powerful front-rower is a former member of the England Under-18s squad and also made his full international debut for Ireland in the 2014 European Championship.
A strong carrier of the ball, Mulhern also possesses an offload game and will be looking to establish himself as a first team regular in the Kingstone Press Championship.
