The Eagles had a good first quarter and scored 16 unanswered points in the 1st quarter, but were unable to muster any points afterwards. In the third quarter, quarterback Sam Bradford left the game with a concussion along and an injured shoulder, while leading rusher Ryan Mathews left with a concussion as well. Mark Sanchez took over as quarterback for the game's remainder and led the Eagles into field goal range. Sanchez was an improvement over Bradford in some ways, mainly mobility and avoiding sacks, but he was also a less accurate passer. He was intercepted in the end zone while attempting to give the Eagles the lead, on a pass that was wrestled away from wide receiver Miles Austin in the 4th quarter..
