There was only one player on the Colts' offensive line whose status was up in the air for the 2019 season.
However, Chris Ballard decided to immediately address Mark Glowinski's future with a three-year contract:
Glowinski, who turns 27 in May, started nine of eleven games for the Colts this season (including both playoff games) after being let go by the Seahawks. The former fourth-round pick has 28 starts and 46 games under his belt in four NFL seasons.
His inclusion on next year's roster means that the Colts currently have all five offensive line starters from a year ago under contract for 2019.
