"A few years ago that was just a telling off. He got a bit of the ball and he got a bit of the man," said the Foxes boss after the controversial 2-1 defeat at Bramall Lane.
"The game changed on the sending off. We looked as though we'd scraped a point but we didn't see it through to the end."
"But I'm very proud of my players. The boys have worked really hard and we're not out of the championship race yet."
