Griffiths was banned for two matches after being sent off and giving the referee a serve in Perth's 2-2 draw with Newcastle.

It was the first red card the 28-year old has picked up in his long career in Australia, Europe and China, while he has received 38 yellow cards in six and a half seasons in the A-League.

Griffiths said he won't alter his game.

"No, I'm in there to break up play and try and intimidate and by physical as a footballer," he said.

"Obviously its copped me a red card unfortunately but that's been my playing style and it's the first red card I've ever got, so I'm not going to change at 28."

Griffiths missed Glory's win over Melbourne Victory and their loss to Central Coast. The former Roda JC man admitted it was hard to watch from the sidelines.

"I think its probably the worst thing ever, especially when I watched it last week when they beat Melbourne Victory," he said.

"Obviously I was happy that they won, but to not have any influence or anything like that over the boys was pretty tough. Last week losing as well was difficult, but back in this week so hopefully the coach picks me."

Perth will face the Jets at home on Saturday without first-choice goalkeeper Liam Reddy who has been suspended.

"'Rocket's' had a great season," Griffiths said.

"But like anyone, it's a good chance for someone to step up and take his place. It's another chance for us to rectify what happened last week."

Both Newcastle and Glory are fighting hard to stay in the top six. Only one point currently separates them on the A-League ladder.

"The A-League's a strange league," Griffiths said.

"You can lose one week and then win the next week and be back up amongst it again and it's the same this week. If we'd have won last week we would have been on the same or equal, or close to Melbourne City, which people didn't anticipate.

"We want to be in the top four - that's what everyone's aiming for. A win on the weekend puts us right amongst it."
