"coming-together at an unusual angle".

On Matic's reaction, Mourinho said: "What are the consequences of his push? Nothing. The consequence for Matic from the tackle? It could be the end of his career."

In a 10-minute interview external-link with the club's video channel, Dyche said comments about the incident had "gone a bit too far" and that he wanted to "give a balanced view, retrospectively, with the evidence we have got and my opinion".

He said: "Ashley Barnes tries to play the ball to Dave Jones. His momentum and pendulum motion of his leg swings up through the ball and unfortunately Matic is late arriving on the scene - not in a vicious way.

"Please everyone look at the reaction from a bunch of expert footballers on the Chelsea side, like Johnwith slow-motion, now there's statements like 'criminal tackle' and the like being used.

"It's a real tough one. I find it hard to believe that all of those people who have now come out with - especially the manager - very strong phrases about that moment, had no reaction at all, at that live moment."

The FA external-link confirmed that because referee Martin Atkinson saw the incident and took no action at the time, it will not be "re-refereeing" the challenge.

Atkinson will not referee this weekend, with a shortened fixture list because of the Capital One Cup final between Tottenham and Chelsea, a game Matic now looks set to miss.

Former referees' chief Keith Hackett believes Atkinson needs a rest after describing his performance in the game as "incompetent".
