Casey went down with a knee injury during the opening quarter of the Bombers’ heavy loss to reigning premier Temora at Nixon Park on Saturday.

Casey did not return to the field and was hardly optimistic after full-time.

“I got my legs taken out from underneath me and felt a bit of a pop in my knee,” he said.

“It’s similar to what I had last year but not the same.

“I’ll find out during the week.”

Marrar has a short turnaround for Friday night’s Anzac Challenge against The Rock-Yerong Creek.

Cal Gardner, Shane Macintosh and Clint Taylor all hope to return for the Bombers.
