Lukas Jutkiewicz cancelled out Daryl Murphy's opener to force an all-Championship replay between Birmingham and Newcastle in the FA Cup third round.
The away side went ahead at St Andrew's early on when Murphy scrambled the ball over the line.
In the melee, Aleksandar Mitrovic stayed down and was given oxygen before being taken from the field on a stretcher.
Just before half-time, Jutkiewicz levelled things up from inside the area and neither side could go on to find a winner.
