The Buffalo Bills have re-signed reserve OT Kirk Chambers, according to ESPN.com's Tim Graham.  Terms of the deal have yet to be disclosed.

Chambers has spent the past two seasons in Buffalo and has seen extensive playing time at both tackle positions as well as right guard.  With the team releasing OG Derrick Dockery earlier in the day, there is some speculation that Chambers might get an opportunity to compete for a starting spot on the inside, particularly if current right guard Brad Butler moves to the left side.  If not, he'll continue to give the Bills invaluable depth along their suddenly swiss cheese-like offensive line.

Buffalo has already released TE Robert Royal today, as well as re-signed FB Corey McIntyre.
