Williams has five international caps for Wales
Worcester Warriors have made their third signing in a week bringing in Welsh international scrum-half Andy Williams on a one-year deal.
The 29-year-old began his professional career at Bath before going on to play for Ospreys and Newport Gwent Dragons.
Williams, capped five times by Wales, signed for Championship side Moseley in 2009 but spent the end of last season on loan at Gloucester.
"I'm so hungry for rugby. I can't wait to start playing again." Williams said.
"I'm really excited to be playing for the Warriors next season. Looking at the Championship, I can't see why we can't finish top and go back into the Premiership the following season.
"The Championship requires a great attitude and Warriors need to be at the top of their game every week. That is something they can do and I'm looking forward to the challenge."
Williams admits he is also excited at the prospect of playing under Worcester Warriors new head coach Richard Hill, who also began his career at the West Country side.
He has a huge amount of experience and can make key decisions

"During my time playing for Bath, I experienced the huge legacy he has left there. So to be able to work and learn from him will be tremendous."
Richard Hill, who has the task of taking the relegated Warriors back up in to the Guinness Premiership, believes the experience of his new signing will be a great asset for the Sixways club.
"Andy has played at the top level with Bath, Gloucester and Newport Gwent Dragons and is spoken of very highly at all clubs.
"We are extremely focused on giving as much opportunity to the young scrum-half's as possible at Worcester. At both Bath and Gloucester, Andy was always willing to help the younger players.
"He has a huge amount of experience and can make key decisions especially when it comes to the bigger matches in the Championship and this will no doubt rub off on the others."
Williams joins former Bath and Bristol centre Alex Crockett and Oxford University tight-head prop Oliver Tomaszczyk, who both signed two-year deals with the Warriors.
