Odion Ighalo is now a doubt ahead of Nigeria's World Cup qualifying game against Cameroon on Monday after he suffered a knock in the first meeting in Uyo on Friday.

Nigeria head coach Gernot Rohr is wary of risking the Changchun Yatai striker who made way for Kelechi Iheanacho after 61 minutes in their 4-0 success last week.

The 28-year-old travelled with the Nigerian contingent for the World Cup game in Yaounde but had to go through an individual session to ascertain his fitness level in a closed door training on Sunday night at the Stade Omnisports Ahmadou-Ahidjo.

The other striking options for Rohr ahead of Monday's game with Cameroon are Leicester City man Iheanacho and Hapoel Be'er Sheva forward Anthony Nwakaeme.

"Ighalo trained good but if he cannot play we will decide in the last moment because we have two possibilities. We have Kelechi and we also have Anthony. The two forwards are ready to play if Ighalo does not make it back.

Rohr made it clear that Ighalo will be monitored closely as he intends to stick with the same line-up that started in Uyo.

However he does not want to take risks if the former Watford man fails to be fit in time for the World Cup qualifying game.

"We will like to use the same team again but with Ighalo having a little leg problem, we will make a change if he does not recover in time. So that is why we have the two other centre forwards (Iheanacho and Nwakaeme) who are fit and ready to play," he explained.

Nigeria's Super Eagles could secure qualification to the World Cup in Russia should they win in Yaounde and Algeria defeat or draw against Zambia in Constantine on Tuesday.
