Indianapolis Colts star quarterback Andrew Luck is not looking any closer to playing Week 1 of the regular season.

Per The Athletic's Zak Keefer, the Colts “aren't ready to determine whether Andrew Luck will or won't be ready for a Week 1 start.”

Luck, 29, is Indianapolis' former first-overall selection from the 2012 NFL Draft. Since then he's gone on to earn multiple accolades like four Pro-Bowl selections, the league's comeback player of the year last season, and led the Colts to playoff berths in four of his seven seasons thus far.

Nevertheless, Luck has also been bitten by the injury bug, as he has been plagued with various ailments derailing what would be a productive career seven-plus years in. The Stanford product dealt with multiple shoulder injuries along with a lacerated kidney, and most recently, Luck is sidelined with a more mysterious injury.

Colts team owner Jim Irsay called it, “a small little bone,” in an interview with ESPN published Tuesday morning.

Luck played in every regular-season game for the Colts in 2018 after missing the entire prior year—recording 430 completions for 4,593 yards, 39 touchdowns, and a 67.3% completion rate.

So far in the preseason, the midwest franchise has seen sequences under center featuring QB's Chad Kelly, Phillip Walker, and Jacoby Brissett.

Kelly, 25, led the Colts in passing attempts and completions in their exhibition loss to the Buffalo Bills last week, throwing 13/19 for 121 yards. Kelly is a former seventh-round pick of the Denver Broncos who signed with Indianapolis in May of this year.

The 24-year-old Walker was picked up by Indianapolis as an undrafted free agent two years ago when he was signed to the practice squad.

Brissett has been on the Colts since 2017, backing up Luck. He has appeared in 20 games over the course of the last two seasons in a Colts uniform.
