Storm CEO Brian Waldron confirmed that Inglis was at a pub in the suburb of Williamstown that evening with his girlfriend, but refuted suggestions he had behaved inappropriately.
"At around 10pm Greg's girlfriend was verbally insulted by a member of the public," Waldron said in a statement.
"Greg took offence at the manner in which his partner was spoken to and a brief verbal exchange took place.
"After nothing more than a few heated words, Greg and his girlfriend left the establishment.
"The Melbourne Storm has investigated the incident fully and, after speaking with all relevant parties including the hotels management, we are more than happy with the way Greg conducted himself at the time.
"We trust this will bring to a conclusion any speculation on the matter."
It was alleged on Melbourne radio station 3AW on Thursday morning that Inglis was involved in a violent altercation.
The Australian and Queensland star has yet to play this year as he recovers from shoulder surgery.
Last month, he was publicly criticised by senior Storm officials after being caught up in a fight in a Brisbane nightspot.
Even though he escaped injury and acted as peacemaker in the altercation, club officials were upset he was out drinking while his teammates were in England preparing for the World Club Challenge final against Leeds.Like
