JACKSONVILLE, Fla. (AP) - Authorities say a skydiver was forced to make an emergency landing when his parachute failed to open during a Jacksonville Jaguars halftime show.

The unidentified parachuter was not injured.

Authorities say the main chute failed to open Sunday and the skydiver was forced to use a backup parachute. He landed safely on the practice field next to the stadium and was not hurt.

Several witnesses who were in the stands for the game took photos. One shot shows the skydiver still in the air after deploying the backup parachute. Another shows him walking off the field.
