Sharks prop Addin Fonua-Blake has been denied what appeared to be a try after the Bunker intervened to overturn the on-field decision, delivering a frustrating moment for Cronulla.

The powerful front-rower looked to have crossed the line, only for the NRL's video review system — known as the Bunker — to rule the try out, leaving Fonua-Blake and his teammates without the four points.

The decision is a significant setback for the Sharks, with Fonua-Blake's physicality and ability to crash over the line a key weapon in Cronulla's attacking arsenal. The Bunker's call adds to the drama of the contest as the Sharks look to find their footing.
