Leicester Tigers will welcome Olly Cracknell to the club ahead of the 2022/23 season.
The back-rower will make the move to Leicester from London Irish.
Capable of playing across the back row, the English-born Cracknell represented Wales at Under-20s level.
The 27-year-old, born in Leeds, is a product of the Yorkshire Carnegie academy and had stints in South Africa with Border Bulldogs and in Wales with RGC 1404.
Cracknell spent seven seasons with the Ospreys, which included a call-up to the Wales senior squad for the 2017 Six Nations, before joining London Irish this season.
Speaking about the addition of Cracknell, Leicester Tigers Head Coach Steve Borthwick said: “Olly is a tough, uncompromising, physical and abrasive player who can play across the back row.
“Each time we have spoken, I have been hugely impressed with how much he wants to be part of what we are building at Leicester Tigers.
“Olly is a competitor and we feel he is the type of player and person that we want representing Leicester Tigers.”
Discussing the move to Tigers next season, Cracknell said: “I was flattered when I had the interest from the club and, after meeting with Steve Borthwick and Aled Walters, I was so impressed.
“It is an environment where people improve and that is where I want to be. Knowing I will be somewhere I can improve and learn is a big thing for me.
“The fanbase Leicester Tigers has is incredible and the history around the club enormous.
“Tigers is a massive rugby club, you can see that, and I am really excited to be a part of it.”
