Christopher Noteboom, of Tempe, Ariz., ran onto the field holding a plastic bag, leaving a cloud of fine powder behind.
As he reached the 30-yard line, he dropped to his knees, made the sign of the cross and laid down on his stomach. Security personnel reached him moments later and he offered no resistance as he was escorted from the field.
The 33-year-old Noteboom, a native of Doylestown, said his mother died of emphysema in January 2005, shortly before the Eagles' Super Bowl appearance.
"She never cared for any other team except the Eagles," Noteboom told WPVI-TV after he was released from custody Monday. "I know that the last handful of ashes I had are laying on the field, and will never be taken away. She'll always be part of Lincoln Financial Field and of the Eagles."
Noteboom, a bar owner in Arizona, was charged with defiant trespass. He has a hearing scheduled for Dec. 27.
"It's bizarre, but we have a zero tolerance for people who run on the field," Police Inspector William Colarulo said. "We especially have a zero tolerance for people who run onto the field and dump an unknown substance in a stadium full of people."
Eagles spokeswoman Bonnie Grant said the team has declined requests to spread ashes on the field.
