Representatives from three NFL teams were present at Grand Valley State's pro day on Monday.
A total of nine prospects -- eight from Grand Valley State and one from Ferris State -- worked out indoors on FieldTurf.
One of those prospects is a potential free-agent pickup for an NFL team following the 2015 NFL Draft.
Defensive lineman Isiah Dunning (6-foot-1 1/2, 289 pounds) ran the 40-yard dash just once, doing so in 5.08 seconds. He had a 29 1/2-inch vertical jump and a 9-foot-2 broad jump. He did the 20-yard short shuttle in 4.74 seconds and the three-cone drill in 7.89 seconds. He performed 23 reps of 225 pounds on the bench press.
