Waratahs and Wallabies forward Tolu Latu will meet with Rugby Australia's integrity unit in Sydney on Monday over a reported drink-driving charge.
The 12-Test hooker played in the Waratahs' gutsy win against the Reds at Suncorp Stadium in Brisbane on Saturday night but was sent home on Sunday morning instead of joining his Wallabies teammates for a three-day camp at Ballymore.
He will meet with RA's head of integrity, Gerard McEvilly, and NSW Rugby boss Andrew Hore on Monday morning, an RA spokesperson said.
One of the first questions he could face is why he did not tell either of his employers, RA and NSW Rugby, of the charge.
It was revealed by News Corp on Saturday afternoon, more than 48 hours after the alleged offence.
Rugby Australia has discretionary powers under its professional players' code of conduct to sideline the former Wallaby until the investigation is complete, AAP reported.
He still took the field for NSW, with Hore telling Fox Sports after the game on Saturday night that Latu was still eligible to play under the code of conduct.
Hore said it was very disappointing to have the matter come up at the same time the team was trying to cope with the storm around Israel Folau's sacking.
"Very [disappointing] and it's something that we'll talk to Tolu about as we go through the investigation," he said.
The NSW Waratahs at least can approach the last throes of the Super Rugby finals scramble with fresh confidence after another scandal failed to sink their title chances.
Thanks to the reliable boot of Bernard Foley, some desperate tryline defence and some late scrum victories against the Reds pack, the Waratahs have moved back to within one victory of the top of the Australian conference.
"To get over in a tight one was nice," captain Michael Hooper said.
"It's been all too familiar looking up at the clock at 70 minutes and the game's in the balance. It feels like that for most of our games this year." with AAP
