Mark Glowinski has returned to the Colts. The veteran offensive lineman signed to Indianapolis’ practice squad on Thursday, per a team announcement. 
Glowinski has 124 starts to his name in the NFL; 59 of those (including 55 starts) came during his first stint with the Colts. The former fourth-rounder was with Indianapolis from 2018-21, handling right guard duties during that time. He landed a three-year, $20MM Giants deal in free agency based on his Colts success.
The 32-year-old played a pair of seasons in New York, operating as a full-time starter in 2022 but seeing his usage drop last campaign. Glowinski was let go in a cost-shedding move in March, leaving him on the open market. That remained the case deep into the season, but he will now return to a familiar environment for the second half of the year. The West Virginia product could be used as a gameday elevation up to three times before the Colts would need to sign him to the active roster.
Will Fries began the season as Indianapolis’ starting right guard, but a leg injury which required surgery landed him on injured reserve last month. Undrafted rookie Dalton Tucker has stepped into a first-team role since Fries went down, but his PFF evaluation has left plenty of room for improvement. Glowinski could reprise his role as a starter opposite left guard Quenton Nelson, or at a minimum provide the Colts with experienced depth along the interior.
In a corresponding move, cornerback Tre Flowers was released from Indianapolis’ taxi squad. The 29-year-old has made four appearances for the Colts this season, and late October marked the most recent point at which he signed to the team’s practice squad. Flowers has yet to see any playing time since, and he will now seek out an opportunity elsewhere.
