Tottenham midfielder Mousa Dembele faces a lengthy ban from the Football Association for his eye-gouge on Diego Costa.
Shortly before half-time at Stamford Bridge, Danny Rose clashed with Willian to trigger a brawl between both sets of players.
The incident was missed by referee Mark Clattenburg but television replays showed Dembele sticking his finger into the eye of the Chelsea striker.
First-half goals from Harry Kane and Heung-Min Son had put Tottenham ahead at Stamford Bridge.
Mauricio Pochettino's men require a win over Chelsea to remain in the title race, otherwise Leicester City will be crowned champions. - Goal
