Stuart-Smith has had limited first-team chances at Stradey

"We obviously wish Clive the best in his future career," said Scarlets director of rugby Phil Davies.

"We respect his wishes that he wants regular first-team action and would like to thank him for his efforts over the past two seasons."

The 23-year-old joined from Worcester, but saw his chances restricted by Dwayne Peel and youngster Liam Davies.
