Redskins spokesman Karl Swanson said there was a disturbance in the fan area a few rows up behind the Philadelphia bench.
Swanson said a Prince George's County police officer intervened and that a "small amount of pepper spray" was used to move the fans back. The cooling fans on the Philadelphia bench helped spread the spray quickly.
"The first guy that went down was Ike Reese," Philadelphia head coach Andy Reid said. "He started
barfing, and we all just followed right along. We just walked onto the field, and I just told them to keep going."
