Kenya have been invited to play the North African side in an all expenses paid duel slated for Tunis, Tunisia, because of security reasons.
Nandwa had earlier told Goal.com that he hopes to field his strongest squad - including Mariga - during the tie.
"We will try and contact Mariga and see whether he will be available. It is unfortunate that he (Mariga) has not been getting enough playing time since returning from injury but hopefully we will get his release for the friendly.”
A source close to the Italian-based player says he will honor the call up. "Mariga is available for selection. He loves Kenya and playing for Harambee Stars excites him. If he is procedurally invited, he will honor the call up."
Mariga last donned Harambee Stars jersey in October 2011, during Kenya's Afcon 2012 qualifier against Uganda Cranes in Kampala. He later opted out of the Afcon 2013 qualifiers following a dispute with the Kenyan FA. A long term injury suffered while on club duty also delayed his return.
Kenyan captain Dennis Oliech, Mariga's younger brother Victor Wanyama, as well as Arnold Origi, Patrick Osiako, Patrick Oboya, Brian Mandela, Jerry Santos and Hiumprey Mieno are the other foreign-based players expected to be considered for the North African trip.
