Sligo Rovers have completed the signing of left-back Calum Waters on loan from Kilmarnock until 10 June, subject to international clearance.
Waters began his career at Celtic and had spells at Dumbarton and Alloa Athletic, with a breakthrough season with the latter leading to a move to Killie last summer.
He has been a regular in the first-team squad at the Scottish Premiership club and switches to Rovers for four months with a view to more game time.
Lyttle said: “It’s another signing that comes with terrific pedigree. Left-back was obviously a problematic position given Regan Donelon had no competition. We wanted to get another player in that area to strengthen the squad.
“The injury last weekend to Regan shows what can happen. While he should be back in the next week or two, we want more than one player per position as we said.
“Calum has come through the leagues after leaving Celtic to get back to the top flight and played some games with Kilmarnock in the Premiership this season. That’s a very good level. He has that hunger – as shown in going to the two clubs and being in the league team of the season at Alloa to get that move.
“He joins us now with his ambition to be a regular with Kilmarnock in the future. He has great energy and will attack from left-back when the opportunity arises which is what we want.”
Waters said: “It’s good to get out and get games. It’s good experience and the League of Ireland has shown itself to be a platform for players to show what they are about.
“It has been a bit stop-start at Kilmarnock so joining Sligo will hopefully help me get a consistent run in a team. I’m the type of player that fights for every ball and gets up and down the line all game.
“It’s ideal that there are 20+ games to be played in my spell here. There’ll be other players trying to get in the team but I’ll be pushing to start as many as I can.”
Lyttle, meanwhile, said there could yet be one more move for Rovers before the close of the window.
“We’re looking for one more player. The deadline is only hours away but we’re doing all we can. We’ll know before Friday’s game.”
