Haas back training with Blues after ankle injury scare

The Blues are already without injured middle forward options Reagan Campbell-Gillard and Jake Trbojevic.

They could ill-afford to lose the bullocking and experienced Haas, especially given two debutants will start in the forward pack at Adelaide Oval on Wednesday night.

The Blues were unsure of Haas' prognosis immediately after training on Friday but will breathe a sigh of relief after the front-rower returned to the field.

The Brisbane behemoth ran freely at the Blues' final session before flying to Adelaide on Monday morning, and participated in the same light contact drills as his teammates.
