QPR have signed Nottingham Forest midfielder Jack Colback.
Colback has moved to Loftus Road on a free transfer, signing a two-year deal.
"Success in this division takes a lot of work, you have to be ready to do the ugly side of the game," former Newcastle trainee Colback told the QPR website.
"That's the difference between the two levels in terms of the Championship and the Premier League.
"There's a difference in terms of the tactics, too. In this division you will come up against teams who want to play football a lot, and you will come up against teams who will be in your face and more direct, which is something you don't get as much in the Premier League."
