Jayden Seales, the West Indies fast bowler, will rejoin Sussex for the start of the 2025 county season.
Seales, who claimed nine wickets in last week's second Test against South Africa, will be available for selection for the first block of the County Championship fixtures.
Seales featured in the first seven of Sussex's Championship matches this season, taking 38 wickets at an average of 25.29.
His best figures of 5 for 29 came in a brilliant spell against Derbyshire, which helped Sussex to an innings and 124-run victory, to cement their place at the top of the second division in the County Championship.
He went on to impress in the three-Test series against England, claiming 13 wickets at 27.23, and now has a total of 62 wickets in 15 Tests for the West Indies.
"It is an absolute pleasure to re-sign for Sussex," Seales said. "I have really enjoyed my time there this season and was very excited when the opportunity came to sign again.
"I can't wait to be with the team again and hopefully in Division One next year."
Sussex Head Coach, Paul Farbrace, added: "I am delighted that Jayden has signed to return to Hove next season, he is a fabulous bowler and a high-quality person.
"He showed on many occasions during the early season that he runs in hard every ball, whatever the conditions and situation in the game.
"He gave himself a great chance of success every day.
"Jayden is an incredibly popular guy in the dressing room, and everyone at the club will be delighted to see him back with us next season and we are all delighted with his continual development playing for the West Indies."
