Donovan was due to face off against AIBA World No.8 ranked Quinton Randall in the third and final meeting of the USA versus Ireland Elite series in Manchester, New Hampshire.
However, the Our Lady of Lourdes fighter was forced to withdraw due to illness.
The USA and Ireland ended up sharing the spoils for a finish in the final edition of their three-match international series last night.
Both nations won four contests apiece at the Manchester Downtown Hotel.
Kellie Harrington, Wayne Kelly, Caoimhin Ferguson and Kieran Molloy had their hands raised in victory for the visitors.
The eight-bout meeting, replicating last week’s encounters in Springfield and Boston, was close throughout with five split decisions separating the contestants on a see-saw evening in New Hampshire.
Exactly half of the 30-bout St Patrick’s festival treble-header finished on split verdicts. The USA won 8-4 and 7-3 in the first two internationals to secure overall victory.
The Ferguson and Molloy verdicts fired Ireland into a 4-2 lead with two fights remaining in New Hamshire, but Nikita Ababiy and Richard Torrez claimed the final two wins of the evening for the hosts to level the match at 4-4.
“Performances have been excellent over the duration of the trip. It has been very worthwhile working with Team America and we are extremely happy,” said IABA High-Performance Director Bernard Dunne, the Irish team manager in the USA.
