Saracens prop Matt Stevens will join South African club Natal Sharks from next season.
The former England international, 31, has signed a two-year deal with the Super Rugby side.
"Matt is a great signing for us," director of rugby Jake White is quoted as saying by Sky Sports News.
"With our front row being unavailable during the latter part of the year, due to Springbok commitments, Matt's experience and knowledge will prove invaluable.
"The youngsters in our squad can take confidence from having a senior guy in the front row."
Stevens won 39 caps for England between 2004 and 2012.
