The Philip Rivers comeback story remains on schedule.

The newly unretired quarterback is expected to start for the Indianapolis Colts on Sunday against the Seattle Seahawks, a source confirmed to ESPN. The Colts elevated him from the practice squad to the 53-man active roster Saturday, making him officially eligible to play.

Rivers, who retired after the 2020 season and last played in a playoff game in January 2021, came out of retirement this week to help the Colts address their quarterback situation in the wake of Daniel Jones' season-ending Achilles injury.
