The 30-year old signed a two-year deal with the Tricolours last month which will commence from the 2019 season.
Scans confirmed the winger ruptured his ACL in the Rhinos big 48-22 win over Toulouse last weekend, meaning he will miss the remainder of the 2018 season.
The Rhinos currently sit ninth on the Super League ladder, with the injury to Hall being a massive blow for the club as they continue to push for a finals position.
After suffering the season-ending injury, it sees Hall finish a one club player with 330 appearances for Leeds since making his debut in 2007.
Hall has scored 233 tries for the club which places him fifth on the all time list of try scorers for the Rhinos, and he has also won six grand finals with the club.
The injury will also mean Hall will not feature in England’s three test series against New Zealand in October and November.
