New Toulouse bosses Fabien Pelous and Ugo Mola are surprised that prop Census Johnston is turning out for Samoa on Wednesday.
The tighthead retired from international rugby when he signed a new contract with the Top 14 giants earlier this year.
However Johnston is set to start for Samoa in the historic Test match against New Zealand.
A source told Planet Rugby that Johnston was asked to play for his country following an injury to his brother James, with Census answering the call while he was back in Samoa for a wedding.
Pelous and Mola indicated that they would monitor the situation with possible reprecussions for Johnston when he returns to France.
"We thought that Census had retired from international rugby. The fact that he is playing against the All Blacks is a bit of a surprise and unsettling," Pelous told Rugbyrama.
"But we'll see if it's only this match or if there is a chance of him playing in the World Cup."
Mola added: "When you lose a key player from your squad that should be present for pre-season but is not, there will be consequences."
