All Blacks lock Scott Barrett's case remains under review, after SANZAAR's foul-play committee adjourned last night's hearing, pending further evidence.
During the opening Bledisloe Cup test in Perth, referee Jerome Garcès sent Barrett off just before halftime for a shoulder charge on Wallabies captain Michael Hooper.

Australia made the most of their one-man advantage to claim a record 47-26 win over New Zealand at Optus Stadium.
The result means a Wallabies win or draw in Saturday's re-match in Auckland will see them reclaim the Bledisloe Cup for the first time since 2002.
The hearing began at 7pm Sunday, but SANZAAR told Newshub that the "Foul Play Review Committee has adjourned for further evidence".
Barrett joined Sonny Bill Williams (2017), Sir Colin Meads (1967) and Cyril Brownlie (1925) as the only All Blacks to be sent off during a test match.
SANZAAR said Barrett was alleged to have contravened Law 9.13 and Law 9.17 during the match at Optus Stadium.
Law 9.13 says "a player must not tackle an opponent dangerously", while Law 9.17 states "a player must not charge or knock down an opponent carrying the ball without attempting to grasp the player".
All Blacks fullback Beauden Barrett said his brother was upset with the incident.
"I was sitting next to him in the changing room. Obviously, he's really disappointed and carrying a lot of responsibility on his shoulders at the moment, but these things happen," Beauden said. "We've just got to get around him.
"I reminded him that he's not a dirty player and he realises that too, so he's just disappointed in himself. He's taking responsibility, but these things can happen,especially when you're defending close to the line and players do get in a low position."
The incident also fired up England coach Eddie Jones, after his team beat Wales 33-19 at Twickenham on Monday.
"I thought it was ridiculous. A bloke gets tackled, he [Barrett] goes to be second man in and his shoulder hits his head, and he gets a red card.
"We can't have that in the game. There has to be some common sense applied, but maybe common sense was applied today really well.
"What I'm saying is that we need to have some consistency and common sense. I think it's really important for the game."
