Newcastle fullback Daniel Georgievski says Mariners defender Josh Rose deserved to be sent off in the F3 Derby on Tuesday.
Rose was given his marching orders in the 72nd minute after picking up two yellow cards.
The Jets went on to win the match 2-0 against 10-man Central Coast, with Dimi Petratos and Patricio Rodriguez getting the goals in the final stages.
Georgievski believes the referee got it right in giving Rose his marching orders.
"They were clearcut yellow cards," he said.
"I wouldn't expect someone like Rose with all his experience to do silly fouls like that. Unfortunately that's a red card. It changed the game a little bit but that's not our problem - it's their fault. So it doesn't really matter.
"It was a red card regardless."
Former Victory man Georgievski was seen having words with Mariners coach Paul Okon at full-time.
The fullback explained it was after ex-Jet Andrew Hoole received a yellow card for throwing the ball at him.
"That's why me and Okon were having a few words," he said.
"I just said control your player's discipline - that's really it. Things like that happen in football, frustration. It's a part of the game, you just have to try and take control of that."
New signing Rodriguez bagged a goal on debut. Georgievski is expecting big things from the Argentine.
"It's very promising signs for Newcastle fans to see what he can produce when he gets fit," the 29-year-old said.
"He's blended in really well. Since he came in he's worked very hard to get fit. I'm very happy for him, he's a nice guy."
