Harambee Stars captain Victor Wanyama has joined his teammates ahead of Sunday's friendly match against Mozambique.
The last time the 28-year old midfielder featured for Kenya was during the 2019 Africa Cup of Nations in June.
Kimanzi will be using the match against the Os Mambas to prepare the players for the 2021 Afcon qualifiers, where they are pooled alongside Egypt, Togo and Comoros in Group G.
Kenya will face the Pharaohs and the Togolese in November this year.
Meanwhile, Jesse Were of Zesco United and Michael Olunga of Kashiwa Reysol are expected to join the rest of the players on Wednesday.
Yusuf Mainge of FK Pohronie in Slovakia and Eric Ouma of Vasalund in Sweden have also joined the camp ahead of Sunday's tie at Moi International Sports Complex, Kasarani.
Finally, Wazito FC's Johnstone Omurwa has withdrawn from the squad after he sustained an injury and Kimanzi has summoned Bernard Ochieng as his replacement.
Omurwa's injury is the second scenario which has forced Kimanzi to make a change in his initial squad after Masoud Juma also withdrew and was subsequently replaced by Enosh Ochieng of Ulinzi Stars.
