The side play the Melbourne Rebels this Saturday at 3:35pm at the HFC Bank Stadium in Suva in their Shop N Save Super Rugby Pacific clash.
The injury was sustained during last weekend’s game against the Highlanders, forcing Valetini to leave the field early.
Valetini, who kicked the winning penalty against the Crusaders in Lautoka, is known for his impact off the bench.
His absence is expected to be felt by the Drua, who are set to face a tough challenge against their upcoming opponents.
