Ipswich manager Mick McCarthy denied he had sworn and directed an offensive gesture towards the travelling fans while celebrating Luke Chambers' goal in the East Anglian derby with Norwich.
Chambers headed in Martyn Waghorn's corner with just a minute of normal time remaining, only for Timm Klose to snatch a dramatic equaliser for the Canaries in the fifth minute of stoppage time.
McCarthy had received criticism for his decision to substitute the Dominic Iorfa late on, with the goal coming shortly after the switch.
McCarthy also praised his team's overall performance, despite conceding the last gasp equaliser which sent Norwich supporters in raptures.
Meanwhile Norwich's head coach Daniel Farke admitted the draw felt like a win because of the way his players reacted to going behind so late in the game.
Klose headed in from close range after fellow centre-back Grant Hanley beat Ipswich keeper Bartosz Bialkowski to the ball and crossed from the right by-line.
