Brighton manager Roberto De Zerbi accused Tottenham interim boss Cristian Stellini of disrespect after a fiery clash which saw both coaches sent off.
Spurs secured a vital win in the race for the top four thanks to Harry Kane's late winner, while De Zerbi must now wait to find out if he will be on the touchline for Brighton's FA Cup semi-final against Manchester United.
This game was dominated by tension between the two benches, which began before kick-off when De Zerbi berated his opposite number.
Tempers flared until the hour mark, when a melee broke out and both managers saw red.
