Practice was interrupted for some 10 minutes when an unidentified fan in the top row of the bleachers required emergency care for what an EMT described as a cardiac issue. The EMT, Terry Gardner, was in the stands watching practice when someone yelled for help. Gardner, a Littleton firefighter and a dispatcher for the Concord Police Department, was the first to respond to the man, believed to be in his 30s. An unidentified off-duty police officer also aided Gardner.

After initially receiving CPR, the subject was treated with a defibrillator and then transported by ambulance for additional care. Gardner said he initially believed the man was suffering a seizure, but it soon became apparent that it was a heart issue.

“If not for the machine,’’ said Gardner, “this probably would have been a different outcome.’’

The incident occurred around 10:30 a.m., and Julien halted practice while emergency personnel worked on the man.
