Augustine Pulu has been announced as the new captain of the Blues.
Hooker James Parsons captained the Blues this year as Umaga's men finished ninth, just outside the playoffs.
Coach Tana Umaga said Pulu, along with previous captains Jerome Kaino and Parsons, form part of the senior leadership group.
"Both James and Jerome are sidelined for some time from surgeries and I wanted our captain to take the reins on the paddock from day one of training," said Umaga.
"Of course both James and Jerome will continue to play invaluable leadership roles in this team and will be key contributors in all aspects.
