WESTS TIGERS coach Tim Sheens believes officials could resurrect the five-minute sin bin after the controversial dismissal of fullback Tim Moltzen yesterday.

Moltzen was binned after being penalised for stripping the ball from South Sydney halfback Chris Sandow just 12 minutes into yesterday's encounter at ANZ Stadium, and while the Tigers eventually won comfortably, Sheens was still baffled by the decision.

"Very ordinary," he said. "It's a bit of a worry in the game the 10-minute thing.

"I can maybe understand a five-minute sin bin, but in the context of the game, the score, the fact that they were no certainty of getting a try, 10 minutes is very ordinary in my opinion."

Moltzen was just the fifth player to be sin-binned this season, with Tigers assistant Royce Simmons maintaining there were similar incidents in yesterday's game.

"It was a very harsh call," he said. "I'll be surprised, if I looked at the video, if there wasn't a couple of other incidents that were exactly the same."

Asked if he felt the 10-in-the-bin rule had run its race, Sheens said: "I think there's an element of sin bin, but maybe a five and a 10-minute one. There's different punishments and different penalties, and I think 10 minutes in the context of an 80-minute game is pretty savage, depending on what you did wrong. For repeat offences there's probably a five-minute bin, which used to happen once upon a time."

Moltzen, who was brought into the side in place of injured Tigers skipper Brett Hodgson, admitted he felt he had let his teammates down but described referee Jason Robinson's decision to bench him as "over the top".

"I was a bit disappointed the way it all happened," Moltzen said. "I didn't think it was worth being sin-binned. I didn't think I had my hand on the ball. I thought Sandow dropped the ball and the next thing I was sitting in the sheds.

"He makes the final decision, but I didn't think it was the right decision.

"The penalty was something that shocked me, so 10 minutes was a bit over the top, I thought, especially at that time of the game - it was only 12 minutes young.

"I could understand it if I had raked the ball and it was 70 minutes into the game.

"It was a big decision for him to make.

"I felt like I let the boys down, and I was very anxious sitting in here, but they defended really well. I was really proud of their effort."
