Harambee Stars coach Jacob "Ghost" Mulee confirmed the development to Nation Sport.
"With Olunga out we had to find a replacement and Makwata fits in well. He is a good striker with experience and adds quality into the frontline," Mulee said.
Zambia-based striker John Mark Makwata has been called to the Harambee Stars squad preparing for back-to-back 2021 Africa Cup of Nations (Afcon) qualifying matches against Comoros.
Stars host Comoros at the Nyayo National Stadium on Wednesday, before facing off again in the reverse on Sunday in Moroni.
