Colts coach Chuck Pagano announced Wednesday that Luck has been ruled out of Sunday's game against the Tennessee Titans because the quarterback has yet to be medically cleared from his kidney injury.
"Getting better, but not good enough to go out and play a football game," Luck said. "I am disappointed. It's no fun to sit out on the sideline, same thing I've been talking about."
The Colts originally announced that Luck would miss 2-6 weeks when he suffered the lacerated kidney and partially torn abdominal muscle after taking a hit early in the fourth quarter in the Nov. 8 game against Denver.
"Not playing," Luck said when asked about the toughest part of being out. "Football players want to play football and you want to be out there playing. You feel like you're letting your teammates down."
The Colts are not putting Luck on injured reserve, which would officially end his season, because they're holding out hope they can still win the AFC South and make the playoffs. Indianapolis needs to beat the Titans and get help from eight other teams to pass Houston and win the division.
"Guy's a warrior," Pagano said. "Wants to be out there with his team."
