One day before their divisional match with the Houston Texans, the Indianapolis Colts have listed both Andrew Luck and Matt Hasselbeck as questionable.

Luck is dealing with the same shoulder injury that forced him to miss Sunday's 16-13 overtime win over the Jacksonville Jaguars. Hasselbeck started in his place, completing 30 of 47 passes with 282 yards and one touchdown, but is dealing with illness.

Luck has stated publically he expects to start on Thursday after missing a game for the first time in his career, but questionably, according to NFL rules, means he has a 50-50 chance to play.

Should both miss the game, Josh Johnson - signed last week to serve as Hasselbeck's backup - would start for the Colts.

The Colts lead the AFC South at 2-2, while the Texans sit at 1-3.
