In his first season in charge , which was cut short as a result of the September 11 attacks , Dallas lost in the playoff quarterfinals to Jeffries ' former team . For the 2003 season , the Burn relocated their home games from the Cotton Bowl to the much lower capacity Dragon Stadium ( a high school football stadium ) in Southlake , which is a northern Fort Worth suburb . The team performed poorly in 2003 and Jeffries was fired in September . He was temporarily replaced by his assistant , former Northern Ireland international Colin Clarke . The team missed the playoffs for the first time , having been one of only two teams to have qualified on all seven prior occasions
