Dameon Pierce‘s season has come to an end. The Texans have placed the rookie running back on injured reserve, reports ESPN’s Field Yates (via Twitter).

Pierce suffered a high ankle sprain during Houston’s Week 14 loss to the Cowboys, although initial reports indicated that the injury was mild. It was believed that the rookie RB may only have to miss a game or two, which wouldn’t necessitate a move to IR. Instead, the Texans decided to shut down Pierce for the year.

The fourth-round rookie has quickly established himself as an offensive focal point in Houston. He’s started all 13 games for the Texans, and he leads all rookies with 939 rushing yards. In total, the Florida product has contributed 1,104 yards from scrimmage and five touchdowns. With Pierce out for the final four games, the Texans will likely turn to Rex Burkhead and Dare Ogunbowale to lead their RB room. Royce Freeman will also be signed to the active roster, according to Aaron Wilson of ProFootballNetwork.com (on Twitter).

Cornerback Derek Stingley Jr. and defensive tackle Taylor Stallworth are also heading to IR, per Yates. Stingley, the third-overall pick in this year’s draft, hasn’t played since Week 10 while recovering from a hamstring injury. He started each of his nine appearances for the Texans this season, collecting 43 tackles and one interception. After starting the season in Kansas City, Stallworth got into one game for Houston in 2022.

There is some good news on the injury front. According to Wilson (on Twitter), the Texans have also activated defensive lineman Jon Greenard from IR. Greenard had eight sacks in 12 starts last season, and he started each of Houston’s first four games this year before landing on IR. To round out their moves, the Texans signed defensive back Jacobi Francis to the 53-man roster and have promoted defensive back Will Redmond and tight end Mason Schreck from the practice squad.
