The Premier League opener between Liverpool and Bournemouth was stopped in the first half after Cherries forward Antoine Semenyo reported being racially abused by someone in the crowd.
Referee Anthony Taylor stopped play at a 29th-minute Liverpool corner before talking to both managers on the touchline.
Liverpool and Bournemouth captains Virgil van Dijk and Adam Smith were then called over to the benches to be briefed before the match resumed four minutes later, while the score was 0-0.
An anti-discrimination message was read out to the crowd inside Anfield once the half-time whistle had blown.
