The secondary will be one of the Lions’ main concern heading into the draft. They brought in cornerback Ras-I Dowling on Wednesday for one of their 30 allotted visits by draft prospects.

Dowling’s size -- he’s 6-foot-2 and 200 pounds -- is something that sets him apart from other cornerbacks.

“I feel I can do a lot more things than a lot of what other corners can do. Just being physical, especially as a tackler. I do a lot of things well,’’ Dowling told the Lions web site.

He played four seasons at Viriginia. But his durability is a question. He only played five games in his senior year.

“It was frustrating, but I feel like things are going to happen. You’re not going to go out and play football and not get injured. Everyone’s going to deal with injuries,’’ he said.

There’s some disagreement where he ranks among prospects. The National Football Post has his ranked as the 20th best cornerback in the draft. While ESPN’s Todd McShay has him going in the second round (51st overall) and Mel Kiper has him going with the 61st overall pick.

If the Lions don’t get Prince Amukamara in the first round with the 13th pick, perhaps they’ll look at Dowling in the second round.
