Jimmy Okello made his List A debut for Ugandan cricket team at the 2007 ICC World Cricket League Division Three. Just after the conclusion of the tournament, he along with fellow Ugandan cricketer, Patrick Ochan were reported missing and later it was revealed that these cricketers were seeking asylum in Australia. The Ugandan Cricket Board later suspended both of these cricketers by preventing them from playing cricket further in the future for the national team by handling life bans to them.
