The 33-year-old defensive midfielder played a crucial part in Nottingham Forest’s promotion-earning campaign in the 2021/22 season.
Colback fell down the pecking order in Steve Cooper’s side last season and left the club after the expiration of his contract with the Premier League side.
A host of Championship outfits, including West Brom, Ipswich, Birmingham City and Queen Park Rangers, lined up as his suitors in the ongoing window.
Despite attracting interest from several Championship outfits, QPR were the first club to make a no-strings attached approach to Colback
And now Gareth Ainsworth’s side have managed to convince Colback to join them, beating strong competition from Ipswich, West Brom and Birmingham.
It has been claimed that the former Nottingham Forest midfielder is set to pen a deal with QPR today.
Now Colback, who has vast experience playing in the Championship and Premier League, will be hoping to help QPR push for promotion next season.
