Sending-off cost us - McKinnon
Dundee United boss Ray McKinnon admitted his side were always up against it after being reduced to ten-men against Hibernian at Tannadice.
The recalled Lewis Toshney was sent-off for a couple of first-half challenges and the visitors soon took advantage when Jason Cummings blasted in what proved the winner.
Goalscorer Cummings was also later dismissed in addition to his manager Neil Lennon, but it didn't stop Hibs from extending their lead at the top of the table.
"It was extremely difficult when we went down to 10 men," McKinnon told BBC Scotland. "I thought we started the game excellently and controlled the first 15 minutes, but the sending-off certainly had a massive impact on the game.
"I haven't seen it again, but Lewis has gone for the ball and then he has pulled out. It was clear for everybody on our bench," he added. "The ref is entitled to make that decision, but we were very disappointed. You have to look at all the decisions that were made and some of inconsistencies and tackles that went unpunished."
