The growing injury concerns surrounding the Super Eagles ahead of crucial 2026 World Cup qualifiers may have increased after captain William Troost-Ekong missed his second straight league game in Saudi Arabia.
Before this absence, Ekong has been ever-present for Al Kholood having played all 20 matches.
The 31-year-old central defender was not listed for his team's 1-0 home win over Odion Ighalo's Al Wehda last Saturday.
Yesterday, he was also not on the matchday squad for the visit to second-placed Al Hilal, where they lost 5-1.
A source close to the player told SCORENigeria that he was back in England this past weekend to celebrate his daughter's fourth birthday.
He is not at risk of a suspension and there was no word about his health status, though.
