FOOTY'S BACK AFL confirms return date

Police are investigating the circumstances that led to the 30-year-old taking himself to hospital overnight.

"Stonnington Crime Investigation Unit detectives are investigating after a 30-year-old Lorne man presented at a Melbourne hospital overnight with a non-life-threatening injury," a Victoria Police spokesperson said.

"Detectives are investigating the circumstances surrounding the incident and hope to speak to the victim again later today."

The Cats released a statement on Sunday morning, saying Steven was in hospital and recovering and that the club's concern was for his health and wellbeing.

"The matter has been referred to police and until their investigations are completed the club will not be in position to offer further comment."

Steven switched from St Kilda to Geelong in last year's Telstra AFL Trade Period in exchange for pick 58. 

He played 183 games and won four best and fairests at the Saints but made only seven appearances last season.

Steven twice took a break from football in 2019 to focus on his mental health, and he tried to cross to the Cats a year earlier.
