Bills center Eric Wood will announce his retirement on Monday due to a career-ending neck injury (Twitter link via Adam Schefter of ESPN.com). The injury is partly due to wear and tear, but one source tells Schefter that it is a “complicated medical situation.” 
Wood, 32 in March, has been Buffalo’s starting snapper since entering the league in 2009. He stands as Buffalo’s second-longest-tenured active player behind defensive tackle Kyle Williams and has been the team’s top center under six different head coaches (seven if you count Anthony Lynn‘s one game as interim head coach.
Remarkably, he started in all 16 of the Bills’ regular season games last season plus their playoff game against Jacksonville. Wood managed to play through the pain all year, but the malady is too serious for him to continue on the field.
Wood graded out as the No. 16 center in the NFL last year, per Pro Football Focus’ advanced metrics. In 2015, the season in which he his first and only Pro Bowl, PFF had him ranked in the top five league-wide.
We here at PFR wish Wood the best as he deals with his medical situation.
Sad news. Wish Eric Wood nothing but the best in his future. I’m sure the Bills Mafia will miss him
