Douglas Costa had broken the deadlock for Juventus early on but the Derby d'Italia would be plauged with controversy minutes later.
Mario Mandzukic had gone down holding his leg following a hard challenge by Vecino, forcing the referee to have a second look using VAR.
The official decided that the tackle warranted further action, showing Vecino a red card and reducing the home side to 10-men with just 18 minutes gone on the clock despite replays suggesting that a yellow would have been sufficient.
