Leeds forward Weller Hauraki has been ruled out for up to three weeks with a calf strain.
Hauraki, 27, picked up the injury in Sunday's 44-16 win over Widnes, although the positive news for him and the Rhinos is that he hasn't suffered a tear.
The Kiwi, who signed from Crusaders at the end of the 2010 season, has already begun rehabilitation with the Rhinos medical team.
He missed just three Super League games for the Rhinos last season, and was an ever present for Crusaders in 2010, scoring 11 tries.
A new name, a new structure, a new knockout tournament and the same trailblazing reputation for expanded horizons will be common themes for Kingstone Press League 1 in 2015.
