Schefter described the injury as "wear and tear" on Wood's neck, as well as calling it a "complicated medical situation".
Wood has since officially announced that he is no longer cleared to play football.
Wood, 31, was taken in the first-round of the 2009 NFL Draft by the Bills after a standout career at Louisville. Wood has played his entire career with the Bills, and he was even selected to the Pro Bowl in 2015.
Wood's injury comes out of nowhere, as the big offensive linemen played every single offensive snap for the Bills in the 2017 season.
Wood was a key part of Buffalo's offensive line this past year that saw the Bills finish sixth in the NFL in rushing offense. The rushing totals helped propel Buffalo to the NFL Playoffs for the first time in almost 20 years.
