Manly officials will speak with young prop Addin Fonua-Blake on Monday after being told he was subjected to racial abuse from the crowd during a match in which he was sent to the sin-bin for a shot on Mitchell Pearce in Newcastle.

Fonua-Blake was on Sunday charged by the match review committee for his 68th-minute tackle on Pearce which forced the Knights halfback out of the remainder of the game with concussion. The Sea Eagles forward will miss two matches with an early guilty plea.

Manly officials were on Sunday yet to speak with Fonua-Blake but had been told by some fans in the grandstand about the nature of the abuse directed at him. The front-rower did not talk to reporters after the match but Manly were told the Tongan powerhouse was subjected to some racial taunts from a small section of the 21,779 supporters.

Once he reached the sideline after being sin-binned, Fonua-Blake raised his arms in the direction of the spirited Knights crowd before cupping his hands to his ears. He continued to bait the fans before he returned to the field with just a couple of minutes on the clock.
