Just days before the start of the season, the Falcons have not made their final decisions at two crucial positions along the offensive line, or they are trying to make the Minnesota Vikings guess about the starting lineup.

The Falcons play the Vikings at 1 p.m. Sunday at U.S. Bank Stadium.

The Falcons list Matt Gono or Kaleb McGary as the starting right tackle. After getting his first action of the exhibition season against Jacksonville, McGary said he didn’t think he was in game shape, but would give it a go if asked.

He had a cardiac ablation procedure July 31.

Also at left guard, the Falcons list James Carpenter or Jamon Brown as the starter.

It understandable that the team doesn’t want to tip its hand to the Vikings and their stout defensive line.

Here’s the first official depth chart of the season:
