Geelong rookie James Toohey has announced his retirement due to personal reasons.

The 21-year-old key position player was in his second year on the Cats’ list, but will return to full-time study after deciding to walk away from his AFL career.

“Due to family, medical and personal reasons, I have decided to step away from AFL football and return to university on a full-time basis,” Toohey said.

“It’s an extremely difficult decision, but one that is the best thing for my health and my family.

“I would like to thank the club for the opportunity, and for all the support they have given me and my family.

“I am unbelievably grateful for the experience and just wish the best for all my teammates and the club.”

Toohey, taken with pick 15 in the 2014 rookie draft, played 13 VFL games for the Cats last year.

He was the dux of his school, St Kevin’s College, in Year 12.

Geelong football manager Steve Hocking said the club wished Toohey and his family all the best for the future.

“James has been a popular member of our playing list and we will miss him,” Hocking said.

“We are happy for James that he has made this decision and have no doubt he will do well in his studies.

“He is always welcome at the club and we wish James and his family the best in the future.”

Toohey’s decision comes just a couple of weeks after the Cats announced midfielder Brad Hartman would move on after taking time away from the club.
