PITTSFORD, N.Y. (AP) Buffalo Bills starting left tackle Cordy Glenn took the next step in addressing lingering soreness in his left foot by receiving an injection.

In announcing Tuesday that Glenn was listed as week to week, coach Sean McDermott said only that the player traveled to Wisconsin to have the procedure done by foot specialist Robert Anderson. McDermott would not disclose the nature of the injury or the injection, which took place a little more than a week after Glenn was examined by Anderson .

"The doctors are hopeful. We're all hopeful," McDermott said. "We're hopeful at this point that this is something that finalizes it and knocks it out and Cordy can return on a full-time basis."
