The Indianapolis Colts enter Week 15 faced the kind of quarterback uncertainty that can tilt a playoff push in either direction. A surprising return, a developing injury, and a shrinking postseason window have created a storyline with more questions than answers.
Who Is the Colts Quarterback for Week 15?
Two practices into Philip Rivers’ unexpected return from retirement, signs strongly suggested the Colts are preparing him to start in Seattle. ESPN’s Stephen Holder reported that his time observing the team this week has “left me only MORE convinced Philip Rivers is this week’s starting quarterback… That player is Rivers. Period.”
Rivers, now forty-four and five seasons removed from his last snap, is attempting to accelerate his readiness for a must-win game against a 10-3 Seahawks team with one of the league’s toughest defenses.
The Colts’ season downturn, following a 7-1 start, has intensified the pressure surrounding this decision. At 8-5 and holding eighth place in the AFC, the Colts’ playoff odds swing dramatically depending on Sunday’s outcome.
According to PFSN’s NFL Playoff Predictor, a win would elevate their chances of making the postseason to 60.40%, while a loss drops them to just 30.10% before facing the San Francisco 49ers the following week.
Further complicating matters was Riley Leonard’s unexpected knee issue. Leonard, who replaced Daniel Jones after the latter suffered a season-ending Achilles tear, informed the medical staff of the problem on Monday. Leonard completed 18 of 29 passes for 145 yards with an interception after entering early in Sunday’s game.
However, on Saturday, NFL insider Ian Rapoport confirmed that Rivers will start for the Colts in Week 15 against the Seahawks.
“The Colts will start QB Philip Rivers on Sunday against the #Seahawks, sources tell The Insiders. Age 44, out of retirement, after a full week of practice, Rivers is a go,” Rapoport wrote on X. “Both QBs took first-team reps this week — Philip Rivers and Riley Leonard. And both could play on Sunday. But Rivers emerges from a wild week as QB1.”

The broader matchup context adds another layer. According to PFSN’s Offense Impact metric, the Colts hold an impact score of 88.9, the second-best in the league, while the Seahawks rank seventh overall with an impact score of 83.0.
Both teams have played thirteen games so far this season. The Seahawks average slightly more points per game, at 29.8, compared to the Colts’ 28.9, but the Colts generate more points per drive and more yards per play.
The Colts have produced nineteen passing touchdowns and twenty-four rushing touchdowns, while the Seahawks have twenty-two passing scores but only fourteen on the ground.
Turnover margins also differ significantly: the Colts have fifteen giveaways compared to the Seahawks’ twenty-three, and although the Colts have thrown fewer interceptions, the Seahawks’ higher production in explosive plays balances that gap. These comparisons underscore that while the Seahawks own the better record, the Colts’ offense has been more efficient overall.
Defensively, the Colts must also navigate the possibility of playing without cornerback Charvarius Ward, now in concussion protocol. Ward’s history of multiple concussions, including a prior incident that left him “getting dizzy for damn near a month,” heightens the concern at a time when Sauce Gardner is also unavailable.
