Forest Green said head coach Mark Cooper denied the alleged jibe against Leyton Orient interim boss Ross Embleton on Saturday

The Football Association will not investigate Forest Green head coach Mark Cooper after it was alleged he made an “unacceptable” jibe about late Leyton Orient boss Justin Edinburgh.

O’s interim manager Ross Embleton was sent off in Saturday’s defeat by Rovers for throwing chewing gum at Cooper.

He claimed Cooper labelled him “an impostor” and asked: “Who do you think you are, Justin Edinburgh?”

Cooper denied the claim and said he was pleased the FA acted “swiftly”.

“I’m pleased the FA have given such a swift and clear statement on this matter,” Cooper said in a statement on Forest Green’s website.
