ACL blow for GWS young gun Paul Ahern

Greater Western Sydney youngster Paul Ahern will spend a second straight season on the sidelines after tearing the anterior cruciate ligament in his right knee for the second time this year.

Ahern hasn’t played a game at any level this season after rupturing his ACL in a training drill in February.

The 20-year-old suffered the same fate on Wednesday morning, as the Giants trained behind closed doors at ANZ Stadium in preparation for their qualifying final clash with the Sydney Swans this week.

It’s believed the injury occurred during a standard training exercise, before¬†scans revealed the worst possible news.
