A Crystal Palace fan has been arrested after invading the pitch to confront Damien Delaney at half-time during Sunderland's 4-0 victory at Selhurst Park on Saturday.
The man appeared to grab the Palace defender's shirt before being led away by security.
Delaney was substituted at half-time, though Palace boss Sam Allardyce said it was not because of the altercation.
Palace players were booed off after conceding all four goals by half-time.
Allardyce said his players deserved to be booed as they fell to a fifth consecutive Premier League defeat at home, which leaves them 19th in the table, two points from safety.
