PITTSFORD -- Cordy Glenn received what the Buffalo Bills hope will finally resolve the lingering soreness in his left foot.
Coach Sean McDermott said Tuesday that Glenn had recently traveled to Wisconsin to receive an injection in the foot from Dr. Robert Anderson, from whom the left tackle had sought a second opinion for the ailment.
"We hope and we're hopeful at this point that this is something that can finalize it and knocks it out, and Cordy can return on a full-time basis," McDermott said.
The coach said Glenn, who has been out of practice for a week, is listed as "week-to-week" and won't play in Thursday night's preseason game against the Philadelphia Eagles. Glenn also missed last Thursday night's preseason-opener against the Minnesota Vikings.
Asked about Glenn's status for the Sept. 10 regular-season opener against the New York Jets, McDermott said, "The doctors are hopeful, we're all hopeful. That said, it's really week-to-week at this point. We hope to get him back as soon as possible."
McDermott said the Bills would continue to have rookie Dion Dawkins work at right tackle, where he is challenging Jordan Mills, and keep Seantrel Henderson at left tackle even though Henderson is due to be suspended for the first five games of the season for violating the NFL's substance-abuse policy.
Meanwhile, wide receivers Jordan Matthews (chip fracture in his sternum) and Jeremy Butler (concussion), and safety Bacarri Rambo (hamstring) also won't play against the Eagles.
McDermott said Matthews is "going to have a couple sore days here, based on the diagnosis." But the coach pointed out that the receiver was "very positive. He's a right-eyed young man with a great smile and we discussed, hey, that helps the healing process."
While acknowledging that Matthews' injury one practice after joining the Bills in last Friday's trade with the Eagles is "a little bit of a blip on the radar," McDermott pointed out that things could be worse.
"There are a lot of players that are lost for the year out there, and we're grateful that's not the case with Jordan," the coach said. "I'm hopeful that he gets back sooner than later and I look forward to having him on the field."
Offensive tackle Michael Ola (toe), cornerback Shareece Wright (thumb), cornerback Kevon Seymour (foot), and defensive tackle Adolphus Washington (back) are listed as questionable, although Seymour practiced Monday and Tuesday and Washington returned to practice Tuesday after leaving Monday's session early.
