Worcester Warriors' centre Will Butler has suffered yet another injury set-back in his promising career as he continues to be hampered by unfortunate injuries.

Butler sustained an ACL injury after just ten minutes of the Premiership Rugby Cup win over Bristol Bears last weekend.

The former England under-20 international has had to endure numerous spells out of the game with a string of serious injuries since being promoted into the senior squad in 2016.

And now the Warriors' Head coach Jonathan Thomas has confirmed that the 23-year-old is set for a long spell on the sidelines.

"Unfortunately he is going to be out for a long time," admitted Thomas.

"That could be his season done and that's obviously really unfortunate for him.

"Buts is a really fine player, who was excited about his chance and I really feel for him but that's the harsh reality of this sport.

"I am sure he will come back stronger."

Butler was one of four players who encountered bumps and bruises in that 68-13 win over Bristol.

Harri Doel, Anton Bresler and Isaac Miller all came off the pitch with HIA issues.

Doel was involved in the red card incident with Charlie Powell and failed his assessment at the time so will not be available this weekend, whilst the other three are in contention.

Hooker Niall Annett was pulled from the side before kick-off with an ankle problem but it is not serious and he too should be okay to feature for this weekend' trip to Newcastle Falcons as the Gallagher Premiership returns.

The likes of Melani Nanai, Rory Sutherland and Ollie Lawrence have been out of action over the last month but all will be assessed ahead of the journey north.

Internationals Sione Vailanu and Duhan van der Merwe are now back from duty but the Scottish winger is a doubt after coming back to Worcester 'a bit sore'.

Tongan Vailauni is said to be fresh and ready to go.

Winger Chris Ashton remains unavailable for selection, with Thomas confirming he could not comment any further.
