Lebanon coach Michael Cheika says his side will wait to receive audio from World Cup officials of Adam Doueihi's sending-off in their loss to New Zealand before deciding on a next course of action.
The Kiwis, powered by the devastating Joey Manu at fullback, were made to work for their 34-12 victory on Sunday in Warrington.
But the talking point will centre on Doueihi's second-half dismissal which could lead to him being ruled out of further World Cup group games.
The Cedars face Ireland next in a match that shapes as a shoot-out for a quarter-final berth.
Lebanon had kicked off in the 60th minute when NRL referee Grant Atkins halted play and ordered Doueihi off the field at the Halliwell Jones Stadium.
Cheika described Doueihi's dissent as an "accumulation of frustration" over what he felt was Atkins' failure to effectively police New Zealand's play-the-balls and kick-blocking tactics.
The Wests Tigers playmaker's outburst was not picked up on the referee's mic, but depending on its severity - and how far Lebanon go in the tournament - it could also impact Doueihi's availability for round one of the 2023 NRL season.
"The World Cup hasn't given us any footage, we have asked for it," Cheika said.
"We're all a bit in the dark.
"It's a shame we can't make that decision now because they're unable to find that footage with the audio on it."
If charged, Doueihi would have the right to appeal against any possible suspension.
His dismissal was a sorry end to a game which at one point looked like it could provide an unlikely upset after an opening weekend of blowout results.
The Cedars were gallant against the heavily fancied Kiwis after scoring the first try through Josh Mansour.
Nelson Asofa-Solomona, Kenny Bromwich and Peta Hiku hit back for New Zealand before Lebanon winger Abbas Miski cut the deficit to 18-12 at the 50-minute mark.
Any hope of a comeback was quelled by tries for Dylan Brown and Manu, with Doueihi's dismissal coming shortly afterwards.
Manu was busy throughout the night and his solo effort - where he scooted from 40 metres out, waltzed past four Lebanese defenders, chipped and regathered for himself - was an early contender for try of the tournament.
"He has shown throughout his career that he can come up with those plays," Kiwis coach Michael Maguire said, adding his side needed to be better at sticking to script.
"We put a bit of pressure on at times but we just didn't stay at it long enough to be able to put (more) points on."
Winger Jordan Rapana, who kicked five goals from six attempts for the Kiwis, rounded out the victory with a late try.
Maguire said halfback Jahrome Hughes and prop Moses Leota should be fit for next week's meeting with Jamaica.
