Greater Western Sydney ruckman Rory Lobb will miss at least a month of AFL, with scans revealing damage to his thoracic spine.

Lobb suffered the injury in the Giants’ victory over Gold Coast, during which he was rushed to hospital because the club feared he’d punctured a lung.

“As the week progressed he was still in a fair bit of pain. We did some more investigation, he’s got a little crack in his thoracic spine,” GWS coach Leon Cameron said.
