“And ‘Chez’ pulled up pretty good. Both of them have. There are no real concerns;it’s precautionary with ‘Turbo’ and we want to make sure we know what we’re dealing with.”

Seibold said he was unsure if there was one particular incident that caused Trbojevic to tighten up before he was brought from the field in the final 15 minutes of the game.

Trbojevic has had issues with his hamstrings in recent years,but enjoyed an injury-free pre-season,and was back to his devastating best in the opening round against North Queensland. He scored Manly’s opening try against the Warriors on Friday night.

Social media footage emerged late Friday of Chan Kum Tong confronting a Warriors fan before the pair were separated by another home supporter.

“The NRL is aware of the video shared on social media and is making enquiries,” an NRL spokesperson said.

This masthead also attempted to contact Chan Kum Tong.

“The only thing I know is there were a couple of supporters who were disrespectful with their language towards Jake Trbojevic,so Gordie asked him to pull his head in,” Seibold said. “That was it from what I understand.”

The Sea Eagles enjoy a nine-day break before hosting Canberra next Sunday evening. Lehi Hopoate will play fullback should Trbojevic fail to be fit.
