Jason Peters' stock might have just skyrocketed.
The Buffalo Bills left tackle is holding out for more money, and his replacement has suffered an apparent left arm injury in tonight's preseason game against the Indianapolis Colts.
Langston Walker, who was switched from right tackle to left tackle because of Peters' holdout, was hurt while pass blocking Colts defensive end Ben Ishola.
Walker was engaged with Ishola when Bills fullback Darian Barnes appeared to run into Walker's elbow as quarterback J.P. Losman rolled left.
Walker went down to one knee and on the field before walking gingerly to the trainer's room for X-rays.
The Bills already were thin at tackle. They went into tonight's game with only four healthy bodies at that position.
