Australian former rugby star Petaia signs for NFL's Chargers
Petaia spent 10 weeks from January learning the game at the International Player Pathway program in Florida, which gives global athletes from other sports the chance to play for one of the 32 NFL teams.
Petaia was signed to play tight end by the Chargers after showcasing his skills to NFL scouts at a "pro day" at the University of South Florida last week.
Petaia, who can play at wing, centre or fullback in rugby, made 31 appearances for the Wallabies and played at two World Cups, in 2019 and 2023.
