Panthers fullback Dallin Watene-Zelezniak will be sidelined for at least three weeks with a hamstring tear suffered in the win against New Zealand Warriors on Friday.

Watene-Zelezniak has been filling in at fullback in the absence of Dylan Edwards, who was earlier ruled out for the season after undergoing a shoulder reconstruction.

Panthers coach Anthony Griffin will reveal his next choice at fullback when the side to face Cronulla Sharks is named on Tuesday afternoon.
