It's unclear what the Bills think about Young and whether the former Heisman Trophy runner up fits their plans. The Bills provided no update after Young met with coaches and held an on-field workout at the team's facility.
A person familiar with Young's travel schedule would only say that the player flew out of Buffalo later in the day. The person spoke on the condition of anonymity because no updates had been provided by the team.
Nelson was one of four Bills receivers to run routes and catch passes during the quarterback's session, and was impressed by Young's appearance and ability.
"He looked good," Nelson said, after honoring a teacher and hosting a discussion at Orchard Park High School. "Big guy. Physical and aggressive. He's in shape. He's definitely in shape working out and working hard."
The visit was Young's first this offseason in a bid to find a new team. Young was not re-signed by the Philadelphia Eagles after completing a one-year contract.
