Nottingham have agreed to sign Rotherham fly-half Juan Pablo Socino on a two-year contract.
The Argentine international, who can also play centre, has been a key player for the Titans this term, kicking 210 points in the regular season.
Socino, 22, said: "Nottingham have big ambitions and I want to be part of it.
"I'm delighted. It's a brilliant opportunity. This season has been successful and I know the move will help my development massively."
Director of rugby Glenn Delaney added: "Juan has been outstanding for Rotherham all season and we look forward to him playing here.
"He brings a huge array of skills that will complement our team as we build toward next season."
