Cliftonville midfielder Ciaran Caldwell has agreed a two-year deal with Glenavon.
Caldwell – who was also being tracked by Glentoran and Crusaders – moves to Mourneview Park as part of a straight swap deal with Glenavon striker Tiernan Mulvenna.
Mulvenna has signed a two-year deal with the champions.
Agreement was reached between the two clubs and both players on Thursday night, with the deals concluded on Friday.
Lurgan Blues boss Gary Hamilton said: “Cliftonville were looking for a striker and we were looking for a midfielder, so the deal suits everyone involved.
“Ciaran is a player I have admired for quite a while, so we are delighted to get him on board.
“We are sorry to see Tiernan leave, but we are probably top-heavy as far as strikers are concerned at the club so the move will be good for him.
“It is a big move for Tiernan and one he is looking forward to, so we wish him all the best.”
Cliftonville boss Tommy Breslin added on the club’s website: “Tiarnan will add an exciting new dimension to our attack and, though he has only been involved in Irish League football for a short space of time, I have been very impressed with what he has contributed to Glenavon and believe he has the talent to flourish in a Cliftonville shirt.
“We’re also bidding farewell to Ciaran Caldwell and we genuinely wish him well as he embarks upon the next chapter of his career. He has been with the Club for a number of years and has been part of many memorable occasions which I’ve no doubt he and our supporters will look back on very fondly indeed.”
It is expected that both players will be available for Monday night’s Wasp Solutions League Cup fixtures.
