The Colts' top priority has always been protecting quarterback Andrew Luck.

That will be especially true Thursday night in Houston against 2012 NFL defensive player of the year J.J. Watt.

Though Watt has only two sacks this season, the Colts (3-2) know how quickly he can change a game and he will be facing a makeshift offensive line.

Starting guards Jack Mewhort and Hugh Thornton haven't practiced this week because of ankle injuries. The solution could be moving veteran Lance Louis, who started last week at right guard, to the left side with Joe Reitz making his first start of the season on the right side against the Texans (3-2.).
