A fan donned a yellow jersey, pads and a helmet and briefly found his way past security in an attempt to work out with the Pittsburgh Steelers on Saturday.
According to the Pittsburgh Post-Gazette, the fan -- who was wearing former Steelers safety Troy Polamalu's No. 43 jersey -- was discovered to be an imposter by a team official. Polamalu retired following the 2014 season and the Steelers have not re-issued that number to another player.
