LAHORE Referees, who can be twice the age of the players, sprint across the field keeping up with the players and closely tracking the action. They tend to run 12 miles during the game - five more than the players, said Pakistan Football Federation (PFF)s President Makhdoom Faisal Saleh Hayat during PFF Referee Physical Fitness Test at Punjab Stadium. He said that the journey to becoming a referee in the Pakistans biggest soccer gala -Pakistan Premier Football League - is physically demanding. The PFF sets rigorous fitness requirements for its PPFL referees in a weed-out process that began on 29 August 2010. Such tests should by held after every three month, stressed Faisal while ordering PFFs Secretary General Lt.Col (r) Ahmed Yar Khan Lodhi and Director Youth Development Muhammad Siddique Sheikh.
