The Buffalo Bills should have their franchise left tackle back in time for the season opener, a team source informed The Buffalo News.
Cordy Glenn has missed the first week of training camp with a mystery illness and isn't expected back soon.
But the source insisted he would be "shocked" if Glenn didn't play in at least one preseason game and start at left tackle when the Bills begin the regular season Sept. 7 at the Chicago Bears. The source would not say why Glenn has been sidelined.
Bills coach Doug Marrone and General Manager Doug Whaley have declined to elaborate on Glenn's problem because it's a personal matter.
Glenn is on the non-football illness list. He can be activated as soon as doctors clear him.
A sign the Bills aren't in crisis mode at left tackle is their reluctance to acquire veteran help such as free-agent Eric Winston. Rookie tackle Seantrel Henderson, a wild card with a checkered past that caused him to plummet into the seventh round, has held down the fort quite well so far.
Glenn, the 41st overall draft choice in 2012, started every game last year.
Analytics site ProFootballFocus.com rated him the NFL's 11th-best full-time left tackle. PFF charted him for only two sacks allowed and five quarterback hits.
