Rangers have agreed to sign Accrington Stanley pair Josh Windass and Matt Crooks.
The midfield duo passed medicals with the Ladbrokes Championship leaders early on Wednesday afternoon.
Both men are out of contract at the end of the season and will join their new club in the summer.
Ibrox boss Mark Warburton had been keen for the pair join up with his squad right away as the Light Blues look to push ahead in the promotion race.
It was reported that Rangers were ready to table a bid of £400,000 for the pair. Instead they have been forced to wait until after the season, where they will pay a nominal compensation fee, thought to be around £30,000 for each player.
Windass, 21, was watched by Arsenal earlier this season and has netted 11 goals in 25 appearances for Accrington this term. Crooks, also 21, can play in defence as well as midfield and has seven goals to his name from 24 outings this season.
Warburton has made a swift start to his January transfer dealings after signing up Doncaster winger Harry Forrester and ex-Lech Poznan goalkeeper Maciej Gostomski on six-month deals.
