Roberts had been sent back to Portman Road with a achilles injury which had been suffering with for sometime.
Crewe First Team Coach Steve Holland told the press after Crewe's 0-0 draw against Forest that the paper work for the deal has been done and dusted and would be compleated once the Tractorboys confirmed that Roberts is fit enough.
Roberts was due to have a scan on his heel during the weekend with the results expected on Monday, if the players scan is alright then the player would be incontention for the Vale match this Tuesday.
