The Sydney Roosters have confirmed forward Siosiua Taukeiaho has sustained damage to the cartilage in his left knee, but will not need surgery to repair the injury.
Taukeiaho was named ahead of the Roosters' round six clash with the Rabbitohs last Thursday night, but didn't take the field after sustaining the injury during the pre-game warm-up.
The 26-year-old will now be sidelined for up to two weeks, while he undergoes rehab in a bid to return to full fitness.
Taukeiaho played the first five games of the season for the Roosters, but could now miss games against Canterbury and St George Illawarra.
