Uganda Cricket Cranes captain is out of the squad to tour Namibia this month.
Masaba is out injured and was earlier named in the provisional 19-man squad that has been camping in Entebbe.
In absence of the Right handed batsman, Arnold Otwani has been handed the national arm band.
Gerard Mubiru and Emmanuel Hashya have to wait for their first senior debut after being dropped.
Uganda will face Namibia in five matches (two 50-overs and three T20I matches) before leaving on April 17.
Cricket Namibia confirmed that the tour matches will be played at the Wanderers Cricket Ground in Windhoek.
“The team has worked very hard during the last couple of months in preparation for this tour, we are really excited about Namibia,” said Cricket Cranes coach Laurence Mahatlane.
“We have picked a good mixture of guys who have worked really well for Uganda in the past and some exciting new talent in the group. So hopefully in the next couple of weeks, all these young man will make the country proud.
“Its a good mixture, you have a guy like Franco Nsubuga, who is represented his country for the last 25 years and that is something very very special.”
While in Windhoek, Uganda will reside at The Utopia Boutique, a good team-camping residence that is 38km from the Hosea Kutako International Airport and only a four-minuterive from the City Centre.
Both countries are preparing for challenging engagements in the next months with the Namibians just seven months away from their T20 World Cup campaign in India, while both
countries are preparing for International Cricket Council (ICC) 2022 T20 World Cup qualifying, and are deep into 2023 World Cup pathways events.
Uganda, who have a decisive outing to Jersey this September, are atop of the ICC World Cricket Challenge League B after winning five out five in Oman 2019. Another dominant show will leave them on the brink of playing One Day Internationals (ODIs).
