The Club can confirm that both Canadian international striker Marcus Haber and former Preston and Manchester United defender David Gray have been transfer listed.
The pair join highly-rated midfielders James Dunne and Robin Shroot as players available for transfer.
Haber made 46 appearances for Stevenage last season and scored seven goals. The 25-year old also made his first start for his country last March and scored his first international goal in that same game against Japan. This season he has made five appearances for the Club and also enjoyed a loan spell at fellow Sky Bet League 1 side Notts County, during which he scored twice in 11 games.
Right-back Gray also made 46 appearances for the Club last season and has featured on 12 occasions for Graham Westley’s side this season.
In other team news, striker Oumare Tounkara has been made available for loan.
