Ian Rapoport of NFL Media reports that the Colts are expected to sign veteran QB Josh Johnson to a contract now that they’ve placed Andrew Luck on injured reserve. On Wednesday, the Colts attempted to sign Nate Sudfeld off of the Eagles’ practice squad, but Philadelphia managed to keep him around by promoting him to their active roster. The Colts brought in four free agent QBs for workouts earlier in the week including Johnson, Matt Barkley, Matt McGloin,and Connor Shaw, but it appears as though he was the most impressive of the group.
