A Dallas Cowboys fan roughed up by Philadelphia Eagles fans at their home stadium is challenging the call of the Pennsylvania Superior Court that the team and its security contractor is not responsible for paying him $700,000 for his injuries.

Patrick Pearson sued the Philadelphia Eagles LLC, the owner of the Eagles’ stadium (Eagles Stadium Operators LLC), and the security agency handling public safety during the Dec. 14, 2014, Eagles-Cowboys game for negligence. Pearson went to the game decked out in Cowboys attire, and was jeered while in line for the restroom. He alleged he was subsequently attacked by unruly Eagles fans.
