Victor Moses is facing three weeks out at Stoke City.
The winger limped out of Saturday's defeat at Sunderland after just 18 minutes and won't now be teaming up with Nigeria ahead of their AFCON double-header against Sudan, says The Sentinel.
"I tried to reach him on phone, but he did not pick up. The team secretary reached him and he may now be out for three weeks or so," Nigerian boss Stephen Keshi said.
