On 2 April 2005, Dyer was involved in an on-pitch brawl with teammate Lee Bowyer in Newcastle's Premier League match with Aston Villa, and both had to be pulled apart and separated by their teammates and Villa players. This resulted in Dyer and Bowyer receiving red cards, leaving Newcastle with eight men as Steven Taylor had already been sent-off for a deliberate handball. Dyer was handed a three-match ban by the FA for the sending-off; Bowyer received a four-match ban from the FA and was fined more than six weeks' wages – about £200,000 – by Newcastle. Later in April, The FA increased Bowyer's ban by three more matches and fined him £30,000. In 2006 the Newcastle Magistrates' court fined Bowyer £600 and ordered him to pay £1,000 costs after he pleaded guilty to sparking the brawl.
