The 2020 NRC competition has been cancelled because of the Covid-19 pandemic.
The Drua made the semi-finals in their debut campaign in 2017 before winning their maiden championship in 2018.
Last year they made the semi-finals despite missing a number of their top players.
Senirusi Seruvakula said he wasn't surprised by the cancellation but was hoping other options would be available.
"Our aim was to win it again and I've got all the players that I wanted but it was just disappointing the NRC won't happen," he said.
