Worcester's former France international Thomas Lombard has reversed his decision to leave Sixways.
The inside centre will see out the remainder of his contract after agreeing to stay with the Premiership side for next season.
According to the club's director of rugby, John Brain, Lombard had 'domestic issues' that needed to be resolved and once done so he was happy to remain with the club.
Contrary to what had been reported he had never actually committed himself to join Castres despite the French outfit claiming they had signed him.
"There was always some doubt," Brain said. "Thomas did not actually sign anything for Castres although they announced he had signed for them.
"We were never entirely happy with that situation of releasing a player who is under contract. We were able to resolve some domestic issues which means he is happy to stay and we are very happy he is doing so."
Commenting on Castres' premature announcement, Brain said: "Announcing that a player has signed is something we never do until we have seen the ink on the paper. It can bite you on the backside, which is what has happened in this instance."
Even though the 30-year-old has opted to extend his stay with Worcester into a third campaign, Brain revealed he was still looking to recruit another player for fill the No 12 shirt.
"We are still looking in that position," he said. "We want some strength in depth in our backline because Thomas Lombard and Dale Rasmussen have carried quite a heavy load this year. We have Gary Trueman and Simon Whatling who can play t here but it would improve us if we could sign another back who can play there and preferably somewhere else too."
