Nottingham have added South Africa-born hooker Shaun Malton to their squad for the rest of the RFU Championship season.
The 22-year-old arrives at Meadow Lane from London Irish, while Malton has previously played for the Sharks and been capped by South Africa at youth levels.
Nottingham boss Martin Haag said: "Shaun has fitted in great and comes to us in great shape.
"It will take a while for him to get used to our systems, but ultimately he is the type of player we are looking for going forward, he is match fit, got great skills and had a good character.
"It makes competition for that hooker's position really intense with Joe Duffey, Scott Wright and Ollie Taylor all there."
