Sunderland have issued a statement strongly condemning the actions of a small number of Burnley supporters during their 4-2 defeat at the Stadium of Light on Saturday.
Missiles were thrown into the home end, forcing several supporters to require treatment. The game was briefly paused in the first half to enable supporters to receive treatment and Burnley apologised for the 'unacceptable behaviour' of some of their supporters.
Sunderland say they are supporting those impacted and will meet with supporters' groups on Wednesday to fast track the implementation of additional safety measures.
