England fast bowler Simon Jones has joined Worcestershire on a two-year deal after deciding to leave Glamorgan.
Jones has satisfied Worcestershire about his level of fitness
Jones, 28, starred in England's 2005 Ashes win, taking 18 wickets in four Tests against Australia.
But he has not played international cricket since then because of ankle and, more seriously, knee problems.
"This has the potential of being the club's biggest signing since the days of Ian Botham and Graham Dilley," said club director of cricket, Steve Rhodes.
"He is a proven strike bowler with the ability to reverse swing the ball very effectively.
"He has proved himself at the highest level but what has impressed me most during our discussions is his overwhelming desire to regain his England place."
The 28-year-old hopes the move will provide a fresh start to his career.
"I'm really hungry to get back playing; to prove points to people," Jones told BBC Hereford & Worcester.
"There was quite a lot of interest and I had to turn down a couple of offers because I liked the Worcester offer so much.

"It's never been a financial thing; I wanted a new start and I think Worcester is the best place for me."
Jones said leaving Glamorgan after 12 years had been "very tough".
He continued: "It wasn't a nice feeling when I went in to see the chief executive, Mike Fatkin, to tell him - it was probably the hardest 10 minutes of my life.
"But he respected my wishes. He was obviously disappointed, but it was something I felt I needed to do."
Jones said having so many injuries had been "pulling your hair out stuff" but he was now working to hard to keep himself in "good nick".
And Rhodes backed Jones to put his bad luck behind him as he attempts to force his way back into the Englsnd reckoning.
"Bowlers do get injuries and some people grow out of those injuries. That's what we're hopeful of - I'd rather think of the positives regarding signing Simon than the negatives.
"He has had a history of injuries, but a lot of those have been unlucky; if you look back to to when he did the damage to his knee in Brisbane, that was a freak accident.
"He'll grow out of them, I am sure he will, and we'll see the benefit of that."
He added: "I know that he does want to play for England and the good thing for Worcestershire is that if he is selected for England, then he must have done well in county cricket, so we're going to benefit as well."
