(TMZ) Philadelphia Eagles defensive tackle Mike Patterson is alert and stable at an Allentown, Pennsylvania hospital — after collapsing and suffering a seizure during training camp this morning.

28-year-old Patterson reportedly dropped to the ground and began shaking violently during practice.

Rookie offensive lineman Danny Watkins, a trained firefighter, rushed over to provide first aid while an ambulance was called.

Patterson was taken to Lehigh Valley Hospital, where his agent says he is “alert, doing well, and not in any pain.”
