ORCHARD PARK, N.Y. (AP) — The Buffalo Bills have signed first-round draft pick cornerback Tre'Davious White.

White signed the contract on Thursday, shortly after the Bills completed a three-day voluntary minicamp. He was selected with the 27th pick out of LSU, and after the Bills moved down 17 spots and acquired a 2018 first-round pick in a trade with the Kansas City Chiefs.

White is competing for a starting job opposite Ronald Darby in Buffalo's revamped secondary. The Bills lost starter Stephon Gilmore and No. 3 cornerback Nickell Robey-Coleman in free agency.

Listed at 5-foot-11 and 192 pounds, White was a three-plus-year starter who finished with six interceptions in 48 games.

White says one of the first purchases he will make is a home for his mother, LaShawnita Ruffins.
