Isaiah Thomas will make his debut for the Cleveland Cavaliers Tuesday against the Portland Trail Blazers, Cavs coach Ty Lue said Monday. The guard, who has been rehabbing from a hip injury, will come off the bench, will be on a minutes restriction and will not play the next night against the Boston Celtics -- his old team. Thomas participated in a full-court scrimmage Friday against his Cavs teammates for the first time since the point guard was acquired in a trade from the Celtics for Kyrie Irving over the summer.
