South Sydney superstar Latrell Mitchell left training early on Monday morning in a worrying sign for Rabbitohs and Blues supporters hoping to see him in the Origin decider.

Mitchell missed the first two games of the series with a back injury but was set to return for the Bunnies against Parramatta on Thursday to prove his fitness for a potential Origin return.

The world’s best centre started Monday’s training session with his teammates but headed back inside after about 30 minutes with no word on what the issue was.

A Rabbitohs official was contacted but didn’t have any information, with players to speak later on Monday to explain what happened.

More to come …
