WARRIORS director of rugby Alan Solomons will have up to six players back with "rotation probable" for Saturday’s European Challenge Cup trip to Castres.

Ryan Mills is set to make his 100th Worcester appearance in France with Duncan Weir, Chris Pennell and Matt Moulds all having clean bills of health.

And Solomons is “positively optimistic” over the prospect of being able to select Francois Hougaard and Nick Schonert subject to no knock-on niggles developing from this week’s training.

Having confirmed Mills “will play” in France, Solomons said Pennell and Weir “are both absolutely fine and have taken full parts in practice, they are available for selection” but was slightly more cautious over Hougaard and Schonert.

“They should both be available for selection, both practiced today (Tuesday) and have to come through with no after effects but we are positively optimistic,” said the Sixways chief.

“People are slowly coming back and it is great to see, the other guy who will definitely be available for selection is Matt Moulds.

“He has been taking part in practices progressively over the past two weeks and has taken full part this week so that’s great as well.”

On the prospect of shuffling his side, Solomons continued: "I think we have to look at a bit of a rotation.

"We played on Friday, got on to the plane at 5.30 in the morning and only got back to Sixways at 3 o'clock on the Saturday afternoon and I think everyone was feeling it.

"Bearing in mind we have to travel again, leaving on Thursday to sleep over at Heathrow to get a 7.25(am) flight and we won't get home until Sunday afternoon, it is back-to-back heavy trips."

Warriors will be hoping those better fortunes on the injury front last while awaiting scan results for Matti Williams (abductor) and Dean Hammond (foot) in the 57-14 win at Enisei.

“I think those were the two most serious,” Solomons said.

“They have had bad luck the two of them, you get that sometimes with a number of injuries and there’s not much you can do.

“Both gave good accounts of themselves before they went off, Dean’s was relatively early in the game

“The others were just bumps and bruises, Doddsy (Tom Dodd) should be fine and it was great to see him in his first game of the season. I thought he was terrific and went really well, so did Matt Cox.

“Shilly (Jamie Shillcock) did well and had a massive impact on the game in terms of the tries he scored and was involved in.”

Solomons declared himself content with the display in Russia but reckons this weekend’s opponents will take things to another level.

“We have to keep it in perspective without taking anything away from the side that played, which I thought did really well,” he added.

“Enisei is not a team that plays in a professional league week in week out so one has to take that into consideration and this weekend’s game will be very tough.

“It appeared to me that they didn’t put out their strongest side against the Dragons and they will (this time).

“If you look at their record this year they have been very strong at home and will be determined to put in a strong performance. They fiercely protect their home ground.”
