The Penrith Panthers will be without winger Dallin Watene-Zelezniak for a number of weeks due to a broken jaw.

The 22-year-old suffered the injury in the club's win over the Rabbitohs in Round 2.

While the injury isn't as bad as Broncos winger Jordan Kahu who broke his jaw in three places, Watene-Zelezniak still be required to undergo a procedure to set a splint.

This will see Watene-Zelezniak sidelined for up to six weeks.

The Panthers face the Bulldogs on Friday night and Watene-Zelezniak was named to play.

He'll now be replaced by either Tyrone Peachey or rookie Christian Crichton when the final teams are named.
