Hibernian head coach Alan Stubbs claimed referee John Beaton spoiled their 1-0 William Hill Scottish Cup fifth-round replay win over Hearts by issuing red cards to both sides.
Jason Cummings, who scored in the first encounter at Tynecastle when the Leith side had come from two down to draw 2-2, was booked for celebrating his fourth-minute strike in front of the visiting fans at Easter Road.
In a frenetic second-half, Jambos defender Blazej Augustyn, booked in the first half for a foul on Liam Henderson, picked up a second yellow in the 75th minute for throwing the ball away at a Hibs free-kick.
Moments later, Cummings joined him down the tunnel after picking up another booking, apparently for kicking the ball away, as Jambos players surrounded Beaton.
Asked if the Hearts players had instigated Beaton's decision to send off Cummings, Stubbs said: "There was an element of that. I thought the sending-offs actually spoilt the game a little bit. I thought they were soft red cards in the end. I don't want to see any players sent off. I just thought it affected the momentum of the game for both teams
"I think in the first one, you are always running the risk but I didn't think he (Cummings) did anything wrong apart from stand there. He didn't make any actions towards the fans, he stayed on the pitch."
