The Buffalo Bills have signed first-round draft pick Eric Wood and second-rounder Jairus Byrd, leaving the team with only its top prospect, defensive end Aaron Maybin, still unsigned five days into training camp.

Wood, selected 28th overall out of Louisville, is being counted on at right guard. Byrd, a safety, was drafted 42nd overall out of Oregon. He was placed on the active/non-football-injury list.

Byrd is recuperating from surgery to repair a sports hernia, a person familiar with his condition told The Associated Press. The person spoke on condition of anonymity because the Bills did not release that information.
