Brisbane second-rower Amber Hall has been blasted for the hair pull that has resulted in St George Illawarra star and reigning Dally M medallist Isabelle Kelly suffering an ankle injury.

The Broncos will look to claim a historic three-peat when they face the Sydney Roosters in the NRLW grand final despite one round of the round-robin competition left to play next week.

After the Roosters made it back-to-back victories to open the season with a smash-up of the Warriors on Saturday, the Broncos also stayed undefeated with a drama-charged 18-4 win over the Dragons.

However the day was overshadowed by Hall's ugly tackle on Kelly, whose hair was pulled from behind by Hall before the Brisbane prop fell awkwardly on her leg.

"I've coached a lot of young girls and when you pull someone's hair, you let go. You let go, you don't go on with it," Dragons coach Daniel Lacey fumed.

"I don't think it's a reportable offence, by the rules. But you've seen the consequences of what happened. I've lost my best player and best outside back. She's shattered, she's in a boot.

"Just let go. It's all that needs to be said."

Lacey believed Kelly wouldn't have been injured without the hair-pull.

"It doesn't happen afterwards if you let go. It just doesn't happen. So let go," he said.

If Hall is suspended for the hair-pull or subsequent drop, two games can be served in New Zealand's domestic league next year.

Hall wasn't the only one to come under fire for a dangerous tackle, with skipper Ali Brigginshaw put on report for attacking the legs of Dragons halfback Maddie Studdon in mid-air.

Broncos coach Kelvin Wright had no issue with the Hall tackle, and tried to play down Brigginshaw's shot.

"I thought (Hall) was penalised for pulling hair, but I didn't really have a problem with it," he said.

"And Ali's, I know it looked a bit late. It looked a bit unfortunate."

In an afternoon of carnage, Dragons second-rower Kezie Apps also suffered a knee injury, while Brisbane duo Lavinia Gould and Jayme Fressard also failed to finish the match.

The Broncos were forced to play with 12 players for the final seven minutes of a match that wasn't decided until winger Lauren Brown sealed their place in the decider in the dying minutes.

The round-two results mean the Broncos and Roosters, who also clash in a dead-rubber game at ANZ Stadium next week, will meet each other again at ANZ Stadium on October 25.

St George Illawarra will face the Warriors next week in a battle to avoid the wooden spoon.
