WALES international flanker Ross Moriarty will line up on the blindside flank as Gloucester Rugby make just one change for Saturday's Aviva Premiership fixture at home to Worcester Warriors on Saturday (kick-off 2pm).

Moriarty returning after Rugby World Cup duty with Wales is the only change from the side that started against Saracens last Friday as he takes over from Lewis Ludlow.

The only other new face in the matchday 23 sees on-loan hooker from Bristol, Chris Brooker, named amongst the replacements.

The teams are separated by just one point in the table after two rounds of action, both having won one game out of two to date.

Having both lost last weekend, it's important for both sides to get back to winning ways but Gloucester's Director of Rugby David Humphreys is expecting Worcester to be a tough nut to crack.

"I think Worcester will be another huge challenge for us this weekend. They've come up and made a great start to their campaign with the win against Northampton.

"It gave them the confidence to know that they can compete in this league. Unlike London Welsh the year before, they've more consistency in their squad and haven't had to recruit so much. And they players they have recruited are experienced and have been successful in various leagues in various countries.

"But we know that we will get better and better as we have players coming back from the World Cup and coming back from injury. We're excited about the next few games.

"But, for us, it's all about this weekend. Both teams should be fairly strong without too many injuries. We'll be coming up against a hugely motivated Worcester side, excited by their first derby back in the Premiership.

"We know what the challenge will be. We know how well we're going to have to play to get the win. But, at the same time, we know that if we go out and perform that we're a good team and we can beat anyone on our day.”
