However, further scans have picked up a small fracture in his jaw, which will see him sidelined for at least a month.
This rules him out for the rest of the Waratahs' season, however, will not keep him out of the British & Irish Lions series at this stage.
"Joseph-Aukuso Suaalii sustained a concussion last Friday night in the NSW Waratah’s Super Rugby Pacific game against the Queensland Reds which was managed by the match day medical team," the club said in a statement.
"He was monitored and has settled well from his concussion.
"However, over the ensuing days he developed soreness which has been subsequently investigated and has shown a small undisplaced fracture of the jaw.
"In consultation with specialists, it has been determined that a small operation to reinforce the area is the best path forward."
Suaalii was already expected to miss Friday's clash with the Crusaders as a result of the 11-day stand-down period.
He will now undergo minor surgery with a view for returning in time for the opening Test on July 6 against Fiji
"This is unfortunate for us and especially for Joseph. We wish him all the best in his recovery and return to full health," coach Dan McKellar said.
“We will do all we can to facilitate his recovery in consultation with Rugby Australia to have him in the best shape possible for his availability for the Wallabies.”
The Waratahs will confirm their side at 2pm Wednesday to face the Crusaders.
