West Indian all-rounder Dwayne Smith will return to Sussex for next season's Friends Provident Twenty20, subject to a work permit being granted.
The powerful all-rounder was a key performer in the Sharks' Twenty20 Cup-winning season in 2009, smashing 59 from 26 balls in the final.
Smith's performances in the shortest form of the game have earned him an international recall and his Sussex appearances would be dependent on any duties with the West Indies.
Sussex anticipate Smith will be available from June 16 and are looking for a locum overseas player to represent them in the five matches prior to his arrival.
Smith said: "It's great to be returning to my home away from home and I'm looking forward to representing Sussex in a big way next year.
"My time so far at Hove has been hugely enjoyable and I believe that my cricket has benefited an enormous amount from the coaching and team spirit that is so evident at the county."
Sussex skipper Mike Yardy said: "Dwayne played a huge part in our Twenty20 success last season and it is very important to get a player who can change the direction of the game like he can."
