Paul Bracewell has left his role as assistant manager of Sunderland with immediate effect.
The 54-year-old, who had three spells with the Black Cats as a player, returned to the club in a coaching capacity in 2013, taking up a role within the academy.
Bracewell was promoted to the first-team coaching staff in 2015, becoming assistant to then-manager Dick Advocaat.
He also served in that role under Sam Allardyce and David Moyes.
“It has been a great honour to serve Sunderland AFC as a player, coach and assistant manager for a combined total of 10 years,” Bracewell told the club’s website.
“I would like to thank the club and its staff, but also the supporters for the great backing I have received throughout my Sunderland career.
“I now look forward to the next challenge in my football career.”
