Cordy Glenn missed a second straight practice Friday night with "soreness" in his foot.
The situation could be more serious than that, though, for the Buffalo Bills' franchise left tackle. Glenn recently traveled to Charlotte to get a second opinion on his injury from Dr. Robert Anderson, a highly regarded physician who has worked with several professional athletes, including the Bills' Kyle Williams.
"Cordy went and got another second opinion, ended up going down to Charlotte and was evaluated by Bob Anderson down there," Bills coach Sean McDermott said. "He's got some soreness. We're going to hold him out tonight. Got a plan moving forward and we're just going to take it day by day."
McDermott said it was "too early" to rule out surgery, and that the team is classifying Glenn as day to day.
"We do," expect Glenn back at practice soon, McDermott said.
Glenn was held out of almost all of the Bills' spring practices and had his left foot in a walking boot as he recovered from what the team said was an ankle injury. He participated in the first six practices of training camp -- although he was held out of some team reps -- before missing Thursday's practice. McDermott admitted at that time to being concerned about Glenn's condition, and said the injury was related to what he dealt with in the spring.
The Bills signed Glenn to a five-year contract extension in May 2016 worth up to $65 million. He missed five games last season -- two because of an ankle injury and the final three because of a back injury. With Glenn out in the spring, the team used rookie second-round draft pick Dion Dawkins as the starting left tackle.
That scenario is likely to play out again if Glenn ends up missing significant time. Seantrel Henderson has worked in with the starters in place of Glenn early in training camp, but will miss the first five games of the season because of a suspension.
"We built a foundation over there with Dion," McDermott said. "We know we've got Jordan on the right side and Michael Ola at this point in camp, so we've got some depth at that position. Certainly want Cordy to be healthy and to play to his potential. He can do that when he's healthy. So we're going to take care of this and then look to move forward."
