Mills completed three of nine pass attempts for 36 yards and rushed for 12 yards on one carry in Sunday's 38-30 win over the Colts in Week 18.
The playoff-bound Texans protected starter C.J. Stroud and let Mills close out the second half of the regular-season finale, once it became clear that an AFC South title wasn't in the cards. A healthy Stroud will helm Houston's playoff game next Monday at Pittsburgh. Mills, who filled in earlier this season when Stroud was hurt, finished the 2025 regular season having completing 91 of 159 attempts (57 percent) with five touchdowns and one interception.
