FORGET attempting to force his way back into the Wales fold, Andrew Coombs just wants to make up for a costly mistake by helping Newport Gwent Dragons "flick the switch" to light up their season.

It's been a tough start to the Guinness Pro12 campaign for the Rodney Parade region and the 29-year-old lock/back row forward has had to watch from the sidelines.

He was given a three-week ban for catching international teammate Alun Wyn Jones on the head with his boot in the 17-15 loss to the Ospreys and had to sit out the encounters with Glasgow, Treviso and the Scarlets.

The indiscretion means that Coombs, who missed out on Wales' summer tour to South Africa, has been unable to catch the eye of boss Warren Gatland.

But it's Dragons director of rugby Lyn Jones that the 10-times capped forward wants to impress rather than the New Zealander when he takes to the field against Edinburgh at Murrayfield tomorrow afternoon (kick-off 2.40pm).

"It's nice to feel part of the squad again," he said. "It was an accident, a clumsy mistake and I have paid the price.

"Now I just want to get back on the field for the Dragons and do well, I am not even thinking about Wales.

"We've got some very good second rows here and I am lucky that Matthew Screech and Cory Hill have picked up injuries."

The Dragons beat Treviso with a bonus point but have lost all four other games and are yet to produce a polished performance.

They headed into the season with hopes of pushing for a top-half finish in the Pro12 and avoiding their usual tag as Wales' worst region.

It hasn't gone to plan so far but Coombs remains confident that the Dragons will soon show their quality.

"There's no beating around the bush, we've got a really good squad but we are not playing well," said Coombs.

"I think it's a matter of flicking that switch and when we do that we will prove that we are a good side.

"The players set high expectations and so do the fans. We've made a slow start but there's plenty of time left in the season and we know that when we start playing well we will be hard to stop."
