The striker is out of contract at the end of next season in 2015. Preston are believed to have offered Garner a new deal as they often do with players they wish to keep in advance of contract expiry.
No terms have been agreed by Garner at present although Grayson was hopeful that something would be tied up shortly. National sources are claiming that Brentford and Wolves may swoop if a new deal cannot be agreed as Garner would be a free agent next summer.
