Tight end Garrett Graham is inactive for the Texans. As a result, rookie Ryan Griffin will make his first start Sunday against the Colts at Lucas Oil Stadium. The Texans are down to one healthy tight end. Normal starter Owen Daniels is still recovering from a fractured fibula, while Graham dealt with a hamstring injury all week and did not practice. He entered Sunday as a game-time decision. Fourth-stringer Jake Byrne was released Friday. Matt Schaub will back up Case Keenum at quarterback. T.J. Yates is inactive again.
