Sam was deemed surplus to requirements by Orlando Pirates, and the Glamour Boys, who were in need of a defender, snapped him.
The left-back was injured during pre-season and since then, he has not been given a chance by Amakhosi.
Cross is the current first-choice left-back at the club with Thatayaone Ditlhokwe coming in when need be.
Edmilson Dove is also recovering from an injury, and Happy Mashiane is doing well which has prompted the Soweto giants to send Sam on loan.
