Carlisle manager Greg Abbott is assessing two more trialists this week as Shamrock Rovers duo Craig Walsh and Gary Shaw aim to impress at Brunton Park.
Walsh is an 18-year-old striker who joined Shamrock from Longford Town last season, whilst midfielder Shaw, also 18, has been a regular in Rovers' youth side.
Abbott told the club's official website: "We've heard good things about the lads and it will be interesting to see how they get on. We'll take a look at them and we can then take it from there."
Meanwhile, Abbott revealed that former Shrewsbury midfielder Jake Simpson has ended his trial period with the club.
He added: "Jake had a great 10-day period with us and he is a decent player, hence the reason for keeping him here for so long.
"It looks like he may have a few other options, and we couldn't guarantee him anything at this moment in time, so he's going off to have a look at those. It's been good to have him here and we wish him all the best."
