New Zealand Warriors captain Roger Tuivasa-Sheck will undergo surgery for his injured left knee on Friday.
The 25-year-old was helped from the field during the first-half of the Warriors 27-12 loss to the Penrith Panthers, in the NRL elimination final last Saturday night.

Tuivasa-Sheck has been diagnosed with a medial ligament and meniscal injury.
The club hasn't given an estimated recovery time, although the standard timeline for such an injury can be anywhere from 4-8 weeks, meaning the fullback's participation in the upcoming Kiwis international window is in doubt.
New Zealand host the Kangaroos on October 13, before heading abroad to take on England in a three-test series.
An injured Tuivasa-Sheck missed the Kiwis' mid-season test against England, with Panthers fullback Dallin Watene-Zelezniak wearing the number one jumper.
The quick-stepping fullback bounced back to produce his best form with the Warriors in the latter stages of the campaign.
He was named the club's Player of the Year and is considered one of the frontrunners for the Dally M Medal as NRL Player of the Year.
