Jurrell Casey and Tyron Smith, who are leaving USC early to enter the NFL Draft, joined the Trojans' football seniors, taking to the USC practice field together for one final time at USC's Pro Day.

In front of a large crowd of NFL scouts, general managers, a pair of coaches and media members, the players were put through drills to test their measurables and then got an opportunity to flash their skills during instructional workouts with the NFL professionals.

Here are some of the top photos taken by Neon Tommy photographer Shotgun Spratling during the event at Cromwell Field.
