The Indomitable Lions could face Niger in Tuesday's leg of the second round of qualifiers for the 2018 World Cup in Russia, without Stephane Mbia and Aurélien Chedjou.

Both players' health is a concern to technical supervision.

In the second training session, on Sunday at Mbankomo, Stephane Mbia and Aurélien Chedjou were removed from the group, to work away with the fitness coach of the Cameroonian selection, Philippe Manouvrier.

Both Lions, under the supervision of the French, did a few laps at the stadium before leaving.

Alexandre Belinga is unable to promise that they will be participating at the Ahmadou Ahidjo stadium on Tuesday. Others are also not in superb physical shape since the return from Niamey.

These include Léonard Kweuke and Nicolas Nkoulou. "There are little glitches, but we hope that all these players will be available for Tuesday. If there are some who are unavailable, changes will be made," said the Cameroon technician.
