Former Michigan State cornerback Darqueze Dennard ran the 40-yard dash in 4.42 seconds, and Virginia Tech cornerback Kyle Fuller ran a 4.40.
Dennard is a projected first-round draft pick, and Fuller may join him in that category.
Dennard won the Jim Thorpe Award as the top defensive back in college football.
He was a first-team All-Big Ten Conference who was a three-year starter for the Spartans.
Fuller was a four-year starter, a second-team Walter Camp All-American and a first-team all-conference selection.
