At 28 years old, right tackle Sebastian Vollmer is already starting to show signs of wear and tear.
A back injury kept him sidelined for much of 2011, and he had a "small procedure" on his back prior to the 2012 season.
Now, Karen Guregian of The Boston Herald reports that Vollmer had knee surgery "recently" (ESPN Boston's Mike Reiss later confirmed it took place on Wednesday).
The procedure has been described as routine, but it's fair to wonder whether Vollmer's checkered injury history will affect his value on the open market. There's no denying his talent at tackle, and the need for tackles is always at a premium, but how will teams feel about another note on the rap sheet of injuries?
