It (injury) happened and I have no option but to take it on the chin and work hard towards making full recovery.”"I have been given a two-week rest and I hope to be back ahead of the Caf referees seminar in Egypt in late December, but am optimistic on a quick recovery,” added the former National Bank of Rwanda employee.
