Stevenage have placed striker Marcus Haber and defender David Gray on the transfer list.
The pair join James Dunne and Robin Shroot as players available for transfer.
Canadian international Haber has largely been out of favour this season and enjoyed a loan spell at fellow League One strugglers Notts County earlier in the campaign.
Meanwhile, former Manchester United man Gray could be set to leave Hertfordshire after 18 months at the club.
