ENGLEWOOD, Colo. -- Change appears imminent to the Broncos' offensive line.
Evan Mathis will hit free agency, and with pending surgery, his status could be up in the air for a while, perhaps into the summer, as was the case last year. Ryan Harris is also set to become a free agent after doing yeoman's work at left tackle following a flurry of injuries, and Tyler Polumbus will test the market after seeing rotational work at both tackle spots last year.
Ty Sambrailo will return and appears likely to start at one tackle spot, while questions continue to linger around left tackle Ryan Clady as he recovers from a torn anterior cruciate ligament, but has a $10.
