A Tampa Fire Department official said there was an "indirect lightning strike" in Parking Lot 14 minutes after the game ended and multiple people were knocked to the ground by the force.
The official said four or five other people were knocked down, but declined to be transported to the hospital.
Medics that were staffing the game were the first to arrive on the scene and begin treating the injuries. The official said the age of those who were transported ranged in age from early 20s to above 70.
The conditions of those hospitalized were not available immediately.
