Jack Steven has been cleared of any wrongdoing by the AFL.

The 30-year-old admitted himself to a Melbourne hospital in the early hours of May 17 with a stab wound to his chest.

He was discharged two days later, returned to training the following week and is expected to resume full contact training this week. 

Exact details as to what caused the incident remain unknown. 

"The AFL today said the inquiry into Geelong Cats player Jack Steven suffering an injury to his chest in May has been completed and the matter is now closed," the AFL statement released on Monday afternoon said. 

"As per normal procedure, the AFL Integrity Department waited until after Victoria Police had closed its inquiry into the matter, before seeking details from Steven.

"The AFL Integrity Department is satisfied with Steven’s explanation and has determined there was no breach of AFL Rules or breach of any of the COVID-19 protocols that are currently in place.

"While the matter is now closed, the welfare of Steven remains the priority for the AFL and the Geelong Football Club."

Exact details as to what caused the incident remain unknown, however police confirmed in a statement on Monday evening their investigation was continuing.

"In relation to your enquiry regarding a 30-year-old Lorne man presented at a Melbourne hospital with a non-life-threatening injury on 17 May," the statement said.

"The police investigation remains ongoing and it would be inappropriate to comment further."

The Cats won't provide any further comment, instead leaving the statement to the AFL.

While the Cats haven't officially ruled out a potential club debut for Steven on Friday night against Hawthorn, he is extremely unlikely given the amount of training he has missed.
