Archie Bruce was found dead in his hotel in Toulouse on Sunday after his debut game with second-tier Batley Bulldogs against Toulouse Olympiques.
Bruce, who was 20 years old, was making his first senior appearance for Batley Bulldogs on Saturday.
“We are devastated to announce the passing of our young player Archie Bruce, who was found in his hotel bedroom early this morning, having made his debut against Toulouse yesterday evening,” the Yorkshire-based club said in a tweet.
“Batley Bulldogs, the RFL and the RFL Benevolent Fund will be supporting the family while enquiries by the French authorities continue, with the club squad delaying their return to the UK,” they added.
An autopsy will be carried out by French authorities this week.
A club spokesman added: “Playing the final 30 minutes of the game he made a great impact with darting runs, and his excitement was clear for all to see post match.
“A smart, polite, funny and extremely likeable young man, his death is an absolute tragedy.”
