However Voss refused to blame the contentious decision against Daniel Merrett in the final quarter for his side's nine-point loss at AAMI Stadium on Sunday
Late in the game Merrett marked the ball deep inside Port's forward line and went to kick. However, Merrett stopped and pointed to the Power's Angus Monfries who appeared to be within his protected five-metre zone without a direct opponent.
The umpire called play on and Port pounced, kicking a goal through Chad Wingard that put the Power 10 points up with seven minutes to play.
Voss labelled it only a "small moment" in the game but admitted his initial thoughts were that the umpire had it wrong.
"I'll have to go back and check the vision, but I'm just hoping Monfries was somewhere in the vicinity of one of [Merrett's] teammates," he said.
"Otherwise he was within the five metre area so that'll be an interesting one.
"My first instinct was 'what was Monfries doing standing there?'"
Voss' counterpart Ken Hinkley had a vastly different take on the incident.
The victorious coach was adamant the umpire made the right decision in calling play on.
"I think [Merrett] went, I think he took off," Hinkley said.
