Crewe Alexandra boss Dario Gradi has decided against offering contracts to several trialists - but is keeping two.
Striker Mark McCammon, centre-half Josh Gowling and left-back Curtis Haynes-Brown have all left the club.
The trio featured in the Railwaymen's friendly win over Congleton Town on Monday night, with McCammon netting the fourth goal in a 4-0 win.
Goalkeeper Alan Martin, who played the full 90 minutes at Booth Street, will remain with the club and should figure in Crewe's friendly with Wolves on Saturday.
Matt Bailey will also continue training with the club.
