Wasps have signed Wales international prop John Yapp from Edinburgh.
The 31-year-old spent last season on loan at Wasps' Premiership rivals London Irish, where he played 24 times.
A former Cardiff Blue, loosehead Yapp won his 21st and last Wales cap in the 2011 Six Nations against France.
Meanwhile, Wasps centre Charlie Hayter has been released to take up a central contract with the England Sevens side after making 28 appearances since joining from Moseley in January 2013.
The 25-year-old made his international sevens debut last month when helping England to success at the Moscow leg of the European Grand Prix Series.
He will now stand a strong chance of representing his country at the Commonwealth Games later this month and at the Rio 2016 Olympics.
On Yapp's arrival, director of rugby Dai Young said: "I know John very well from my time with Cardiff Blues and he will add a good level of experience to our front row.
"We now have a good group of props to choose from, who range in experience. We have always sought competition for places and John's arrival will only make that more intense."
Yapp added: "I am really pleased to be joining Wasps ahead of the new season
"I really enjoyed my time in the Premiership last season and I am looking forward to making a real impact in black and gold this year."
