Limerick have signed defender Robbie Williams from Plymouth, while Rochdale striker Craig Curran has joined on loan until the end of June subject to international clearance.
Williams can play across the back four, but has operated mostly at left back in a career that has seen him earn over 200 English Football League appearances with clubs such as Barnsley, Argyle and Blackpool.
Curran, 22, moves from Rochdale having also lined out for Tranmere and Morecambe.
Limerick boss Stuart Taylor said “We are delighted to get a player of Robbie’s talent and experience on board.
"That experience will be of great benefit to us in the team as well as helping the younger players in the squad as well as those I’ll look to develop from our Under-19 squad.”
“It’s an important signing for Limerick FC and a sign of the growing reputation of the club that we can bring in players who are also attracting interest from clubs in the UK.
"It’s a testament to the work the club is doing on and off the pitch.”
