Glenavon's Mark Sykes is expected to join Oxford United after the clubs settled on a transfer fee.
The move is subject to the 21-year-old midfielder agreeing terms with the League One club and passing a medical.
Sykes had looked destined for a move to Port Vale but Glenavon said on Monday that they had received a better offer from Oxford.
Earlier this year Oxford signed Gavin Whyte from Irish Premiership champions Crusaders.
Whyte, 22, has impressed at the English club and in September scored on his Northern Ireland debut against Israel.
The proposed deal for Sykes, announced on Glenavon's website on Monday, includes add-ons for appearances and international caps.
In further transfer news, Warrenpoint Town manager Stephen McDonnell has added three new players to his squad as they continue their battle to avoid relegation.
Goalkeeper Jarad Thompson, 19, joins the Point on loan from Chelsea for the rest of the season and has been capped at Under 18 level by England.
Striker Lee Duffy, 27, moves to Milltown from Drogheda United on a professional contract while Brazilian defender Hernany Macedo Marques, 31, who has previously played for League of Ireland side St Patrick's Athletic, will add experience to side.
"It is good to get some business done early and the guys coming in will add a bit more experience to the squad," said McDonnell.
"We have to kick on and I believe these guys will help us do that in the second part of the season."
