Indianapolis Colts running back Jonathan Taylor has been ruled out of Week 5. The team announced Friday that Taylor, who had been questionable with a high ankle sprain, will officially miss Sunday’s matchup against the Jacksonville Jaguars.

Taylor’s injury is on the same ankle that has seen trouble in the past, with the running back suffering a similar injury in 2022. After missing a few games that season, Taylor re-injured the ankle in December and was placed on injured reserve and underwent surgery, ending his season.

Per multiple reports, this ankle injury is not as severe as the ones in previous years, but Taylor’s recovery time is likely going to be longer than normal given his injury history. Taylor did not practice this week, per the Colts.

Prior to the injury, Taylor had been having a very solid start to the year, running for 349 yards and four touchdowns in the first four games of the season.

Meanwhile, Colts quarterback Anthony Richardson, who has been day-to-day an injury, was downgraded to doubtful on Saturday. Richardson, who was originally listed as questionable on Friday, was limited in practice this week with an oblique injury. Indianapolis is likely erring on the side of caution due to his injury history: The second-year quarterback missed the bulk of last season after undergoing shoulder surgery in October.

Joe Flacco was seen taking most of the first-team snaps during practice Friday, per The Athletic’s James Boyd. With Richardson now doubtful, Flacco is likely to step in on Sunday.
