What's in a number? HoustonTexans.com is taking a look back at the numerical roster of the franchise, and going over every number that's been worn in team history. From the memorable ones like 99, 80, and 4, to some that might not ring a bell, we've got them all covered.

T.J. Yates, QB, 2015

In the second of three stints with the Texans, Yates wore the number six in 2015. On Monday Night Football at Cincinnati, Yates entered the game in the third quarter in place of Brian Hoyer. Trailing 6-3, the Texans were 3-5, while the Bengals were a perfect 8-0. Yates found DeAndre Hopkins in the end zone, who made one of the more dazzling catches of his career, and the 22-yard fourth quarter touchdown would be the deciding score in a 10-6 Texans victory.

Yates would later start at Indianapolis in Week 15, and after completing 6-of-10 passes, would exit the game with an injury. Brandon Weeden relieved him and helped guide the Texans to their first road win against the Colts. In all, Yates would complete 49 percent of his passes for 370 yards over four games that year, and the Texans wound up victorious in three of them.

Yates would play again for the Texans in 2017, and has been an assistant coach with the team since 2019.

He's the only player in team history to appear in a game wearing the number six.

Quarterback Thad Lewis also wore number six, but never took any snaps in a contest.
