Doncaster Rovers have re-signed Ryan Mason on-loan from Tottenham Hotspur.
The 20-year-old, who has signed a two-year deal at White Hart Lane, enjoyed two spells on loan at the Keepmoat Stadium last season.
The midfielder will now return to South Yorkshire on a season-long deal. Mason has been on a pre-season training camp in Portugal with Spurs.
Rovers boss Sean O'Driscoll told the club's website: "We would like, if he is fit to play, for him to feature at Grimsby (on Friday)."
