The West Bromwich Albion player has been disciplined for allegedly leaving after the 4-0 home win over Ethiopia in March, missing the 3-0 friendly win against Kenya two days later.
"Odemwingie left camp without permission after the Ethiopia game," coach Samson Siasia was quoted as saying by his press officer Colin Udoh on his Twitter account.
A Twitter outburst at the coach in March, when Odemwingie accused Siasia of having "issues" with him and tweeted about pressure on him to play in a friendly against Kenya while carrying an injury, overshadowed Nigeria's last two games.
Odemwingie first wrote: "Unlike me my finishing in training today was good. Hearing something that Siasia is angry I left. He needs to think a bit or he got issues."
He soon deleted the comment but then posted: "Managed to play the official (game against Ethiopia). A friendly in an empty stadium (versus Kenya), struggling with an injury preferred not to play. And it became an issue???"
Siasia recalled full-back Yusuf Muhammed, who missed last year's World Cup in South Africa because of injury, to replace Adefemi Olubayo, who died in a car crash in Greece last month.
