The FA has also asked the Terriers for their observations about the new kit.

"The FA has clear kit and advertising regulations for all club matchday kits," an FA spokesperson said.

"If we believe that any club has breached these rules we will look into the matter and, if required, will take the appropriate action."

FA rules state a playing kit is only permitted to have "one single area not exceeding 250 square centimetres on the front of the shirt".
