Giants center David Baas started all 16 games last season, despite multiple injuries that resulted in multiple offseason surgeries. His durability may get an early test in 2013.
Baas limped to the sidelines during the team’s first drive of a preseason game against the Colts.
It has since been announced that Baas was taken to the locker room for X-rays on his knee.
Baas became the starting center in 2011, after six seasons with the 49ers. For his career, he has 119 appearances and 81 starts.
He was replaced by Jim Cordle, who appeared as a reserve in every game last season.
UPDATE 8:03 p.m. ET: According to the game broadcast on FOX, Baas has a sprained knee. Which can mean a lot of things, given the various ligaments in the joint.
