Celtic talisman Daizen Maeda is a doubt for Japan's World Cup party this week after picking up a knock in their derby defeat to Rangers.
The 27-year-old netted his 29th goal of the season for club and country in the weekend loss at Parkhead to Rangers.
He is also a key player now for Japan - who could become the first nation to qualify for the 2026 World Cup if they defeat Bahrain at Saitama Stadium after surging nine points clear of Australia after just six games in their group.
However, Maeda didn't train with the squad and went through his own personal routine and is rated as a doubt for the game.

The Japanese FA stated: "Daizen Maeda did not train with the main group after suffering from a bruised leg and undertook his own individual programme.
"He will be assessed before the game."
Maeda is looking for his fifth goal for Japan in what will be his 23rd cap if he makes it.
