John Carver claims it is because of injuries ... but the 17 year old cannot even get into the first team at non-league Gateshead.
The 17-year-old winger made just three appearances for the Tynesiders in what was supposed to be a loan deal until the end of the season.
Roberts was subbed in the recent home game with Nuneaton at half-time and only appeared as sub against Kidderminster Harriers.
John Carver handed Roberts his full debut in the FA Cup at Leicester City earlier this year.
And it remains to be see whether he utilises the exciting but raw winger in the last 12 Premier League games.
