There is no reason to believe the rookie sensation won't be ready for Sunday's game. In Week 15, Luck and the Colts will be matched up against the Texans.
Fantasy Analysis: Luck struggled mightily against the Titans in Week 14, but managed to squeeze out the win. Unfortunately, team wins don't matter in fantasy football. Luck's consistency may be a question, but he has a lot of upside.
He is going to have plenty of passing attempts, will likely be playing from behind, and is the centerpiece of the offense. Luck is not advisable fantasy play for Week 15 against the Texans.
