After the departure of captain Andy Reid to Sunderland, with Greg Halford coming the opposite way, Pardew has now signed a like for like replacement for Reid in Cook.
Cook was signed from QPR in the summer for £2.5 million, but has struggled with injuries and doesnt look to be in new Cottagers boss Roy Hodgson's plans.
Pardew has now snapped up the 25-year-old and should be in the squad for Saturday's away trip to Scunthorpe, alongside Halford.
