Hayter joined the Scarlets from Harlequins last summer
Hooker James Hayter has left Llanelli Scarlets and is expected to take up a non-rugby job abroad.
Hayter joined from Harlequins last summer on a short-term deal to cover Matthew Rees' World Cup absence.
His stay at Stradey Park was extended when young Scarlets hooker Ken Owens was sidelined by a long-term injury.
"We always knew James had a chance to work abroad in a different profession which he is looking at post-rugby," said Scarlets boss Phil Davies.
"James showed loyal service in his short time with us. In fact James played on many occasions with an injury which illustrates his loyalty and commitment to the Scarlets."
Hayter made 17 appearances for the Llanelli side, the last against Wasps in January.
The Scarlets have also released five of their academy players.
They are prop Ian Jones, hooker Daniel George, winger Alec Jenkins and centres Rhys Williams and Rhys O Williams.
"I would like to thank othe players for their commitment while with the Academy," said Davies. "I wish them all the best in their future careers."
Meanwhile the Scarlets have been linked with a move for Sale scrum-half Sililo Martens.
The 30-year-old - who has 27 caps for Tonga and enjoyed stints with Swansea, Bridgend and Celtic Warriors - could be looking for a new club as Scarlets scrum-half Dwayne Peel joins Sale next season.
