Virginia cornerback Ras-I Dowling pulled out of today’s workouts early with what NFL.com has announced is a strained right hamstring.

Dowling ran a 4.40-second 40-yard dash in his first try. Per the report, it was the fourth-best time among the first group of cornerbacks to run. He did not attempt a second 40-yard dash.

It would be surprising if Dowling returned to do anything else. He’s got the size to be a premium pick for Cover-2 defenses. But durability could be a concern. He missed games due to hamstring, knee and ankle issues last season.
