Johns returned to the National Rugby League in 2002 to play a season with the Cronulla-Sutherland Sharks, before shoulder and neck injuries forced his retirement at the end of the season.
While on a pre-season tour of New Zealand in February 2002, Johns and 11 other unnamed members of the Cronulla Sharks were involved in a group sex session with a 19-year-old in a Christchurch hotel room.
He also played four State of Origin series matches for New South Wales.
Another highlight of his career with the Knights was the 1997 Australian Rugby League grand final victory over the Manly-Warringah Sea Eagles.
“So it’s just like we’re married.”“You’re my TV husband,” Matt explained, his arm around his co-host the whole time.
“And he’s useless at stacking the dishwasher,” he added wryly.
Since 2012, Johns has been a part of the Fox Sports NRL coverage.
He also had his own show for one season, The Matty Johns Show.
Salary cap problems led to Johns leaving the Knights at the end of 2000 to play a season with the UK based Super League club the Wigan Warriors.
Johns played for the Wigan Warriors at five-eighth in their 2001 Super League Grand Final loss to the Bradford Bulls.
He also announced that he was going to be an “actor and entrepreneur”.
