GWS forward Jonathon Patton has suffered a knee injury at training on Thursday with fears he may have torn his ACL, according to a report by Sam McClure.

The club will await results to determine the severity of Patton’s injury, but an ACL tear would rule him out for the remainder of the season.

“The initial diagnosis for Jon doesn’t look positive however we’ll await the results of scans on Friday,” Giant footy boss Wayne Campbell told The Herald Sun. 

“He has the full support of everyone at the Giants during this challenging time.”

The 25-year old has endured an indifferent year for the Giants, playing 12 games and struggling with poor form, which has seen him get dropped to the NEAFL throughout parts of the season.

Patton has torn his right ACL twice before, firstly in 2013 and then again in 2014, but this time it is his left ACL.

It would be a massive blow to GWS’ season, who currently sit sixth on the ladder after being tormented with a series of injuries.

The former pick one has played 89 games since making his debut in 2012, booting 130 goals.
