Sunderland's Irish connections continue to grow as the club announced Irish bookmakers Boyle Sports as their new shirt sponsors.
Boylesports have agreed a four-year, performance-related partnership with the Black Cats which could eventually amount to an eight-figure sum for the Coca-Cola Championship leaders.
The company, which will also provide betting facilities at the Stadium of Light, replaces motor dealers Reg Vardy after eight years.
Sunderland chairman Niall Quinn said: 'We are absolutely thrilled to be joining forces with Boylesports bookmakers to drive the club forward in the next four years, which we think will be exciting times.
'It is fantastic that Boylesports have taken this leap of faith to support us and made a commitment to invest in our future as we continue our efforts to re-ignite the club.'
Sunderland went top of the table with a 2-1 win at Southampton on Monday and are now hot favourites to return to the top flight at the first attempt.
