The NRL have confirmed Grant Atkins has been demoted from his on-field role for Round 26 in the men's competition.

Atkins was in charge of the Newcastle Knights and South Sydney Rabbitohs clash last weekend which at one point saw the Knights awarded a try on what was the eighth tackle.

The NRL's head of football on Monday said it was a "simple refereeing error", offering no mistake for the howler.

Atkins has paid for it with his spot, with Liam Kennedy his on-field replacement this weekend. Atkins will be limited to a single game in the bunker between the Cowboys and Dolphins.

Elsewhere, Ben Cummins will take charge of the critical clash between the Panthers and Eels, while the other games with major finals ramifications, being the Roosters and Tigers, the Raiders and Broncos, and the Knights and Sharks, will be controlled by Todd Smith, Adam Gee and Ashley Klein respectively.

Here are all the appointments for this weekend's action.
