It happened on a night when Tigers fans again voiced their displeasure at the decisions by Mitchell Moses, Aaron Woods and James Tedesco to leave the club.

Fairfax Media understands the incident prompted an angry response from Sharks prop Andrew Fifita, who was seen yelling in the direction of the crowd after the game.

Meanwhile, the Wests Tigers and police are investigating an incident after Saturday night's match between the Tigers and Sharks at Leichhardt Oval in which a projectile was launched in the direction of the players.

Hopoate was originally expected to leave the Bulldogs at the end of the year, but the club's inability to land James Tedesco means they may consider keeping Hopoate.

Despite the club sending an email to members pleading with them to respect their skipper, Woods was once again booed by his home supporters.

There were a number of banners erected taking aim at the players, with Woods called a "dog", Moses "slimy" and Tedesco a "cock" in reference to his expected defection to the Roosters next season. Woods, who on Friday told teammates he would be going to Canterbury, has spoken about his decision to leave the joint venture.

"I just felt let down a bit," Woods said on Fox Sports. "Recently, since Jason Taylor got sacked, it came out publicly that the 'big four' at the time ... that we got him sacked, which is a complete lie.

"The board and CEO make decisions. I didn't get any support, I hadn't heard from the club for three weeks. So I just felt a little bit let down. The club has no stability, like I said before. We didn't know who the long-term coach was going to be but at the same time they wanted us to agree to a three or four-year deal.

"It's my future. I am 26. By the time that contract runs out I am 30. It is a massive decision in my life. That's all I asked. I didn't say go out and sack JT. Once it was done, it was pretty much the four players made the decision which is a complete lie. As I said, I hadn't heard anything from the club for three weeks. You would think they would at least give me a text to see how I was going."
