Sunderland have accepted a deal to move striker Connor Wickham to Crystal Palace, according to multiple reports.
The fee is believed to be in the range of £10 million, the Sunderland Echo reported.
Sunderland paid Ipswich Town £8m for Wickham's services in 2011, and signed the 22-year-old to a new four-year deal in December.
But that was before Dick Advocaat was appointed Black Cats manager in March, and after coming on the Dutchman dropped Wickham into a deeper role.
Wickham scored 11 times for Sunderland in 79 Premier League appearance.
Palace are set to discuss personal terms with the England under-21 international on Friday.
Wickham would be the second striker to move to Selhurst Park this summer after the Eagles agreed a loan for Chelsea's Patrick Bamford.
Sunderland will be left with Jermain Defoe, Steven Fletcher and Danny Graham up front.
