Experienced referee Mick Stone could become the second video official in a week to be demoted from first grade after admitting he made an error in awarding a crucial try to Andrew Ryan in the Bulldogs' win over the Sydney Roosters.

Ryan was given the green light by Stone in the 58th minute of last night's match at Telstra Stadium - won 32-26 by the Bulldogs - despite being in an offside position as he chased a kick from Brent Sherwin.

Roosters coach Ricky Stuart was scathing in his criticism of the officiating after the game and he would have been seeing red today after Stone admitted on Sydney radio station 2GB he made an error in awarding the try.

Stone, one of the most experienced officials in the game, is now under pressure to hold his spot.

Referees' boss Robert Finch said he would go through the decision with Stone on Monday, claiming the video referee was devastated by his mistake.

"He's distraught with the fact that he missed it," Finch said.

"It's not like him but I am sure he will come back bigger and better."

Finch set a precedent last week with his standing down of video referee Chris Ward after he made several blunders in the Canberra-South Sydney game last weekend.

Referee Bill Harrigan initially referred the try to Stone to check whether Braith Anasta had taken out Roosters winger Todd Byrne in the lead-up, with Stone ruling the contact between the pair was legal.

But the video ref missed Ryan being in front of Sherwin and within the ten metres as Minichiello attempted to clean up the kick.
