Earlier this week, Green Bay Packers guard Justin McCray said he could play left tackle if needed Thursday night against the Chicago Bears. It looks like the Packers might need just that. The Packers have only two tackles with experience in their offense, and both are listed as doubtful this week. Left tackle David Bakhtiari hasn’t played since the Packers' opener because of a strained hamstring. Right tackle Bryan Bulaga aggravated his ankle injury Sunday against the Cincinnati Bengals. Without Bakhtiari and Bulaga, the Packers are lean on options. Kyle Murphy (foot) and Jason Spriggs (hamstring) are on injured reserve. McCray, an interior lineman, got snaps at right tackle each of the past two weeks. Stepping over to the left side would be a different world, something McCray said he has done “not much” in his career. But McCray said he’s had practice reps at left tackle the past couple weeks, and wouldn’t hesitate to slide over. “Just a little different,” McCray said. “The footwork is a little different. End of the day, it’s still a similar sort of thing. Different matchups, though.
