Welsh coach Iestyn Harris has said Gareth Thomas will be fit to play in Wales' Four Nations Series debut.
But Harris insists three-quarter Thomas will be fit for the Welsh training camp before their Four Nations warm-up against Ireland in Neath on 22 October.
"He's maybe a week away from full fitness," said Harris.
"It was pointless risking him for the last game of the year and him breaking down again.
"In the next month he'll be fully fit and he'll be ready for the training camp with Wales."
Wales open their Four Nations campaign against England at Leigh Sport Village, the home of Leigh Centurions, on 29 October.
A visit to Wembley to face New Zealand follows on 5 November, before facing Australia on 13 November at Wrexham's Racecourse Ground.
Thomas, who won 100 caps for his country in rugby union, made his international debut in the 13-man code against Italy 12 months ago.
But Warrington stand-off Lee Briers, who missed that match through injury, is expected to regain the captaincy for the Four Nations.
Meanwhile, Thomas has yet to announce his plans for the future following the withdrawal of Crusaders from Super League.
Thomas reversed an earlier decision to retire by signing a new Crusaders contract in June and is currently being linked with a move to Wigan.
But Harris, who is also expected to move to Wigan as assistant coach, said: "You'll have to ask him."
