The Houston Texans were expecting the worst when Lamar Miller was carted off of the field during their preseason bout against the Dallas Cowboys.

A day later, Ian Rapoport of NFL Network is confirming that Miller will be out for the season with a torn ACL.

The Texans running back suffered the injury on the first series of the game for Houston. After the play occurred, Miller immediately grabbed for his left knee and the stadium was silent.

Miller is entering the 2019 season in his fourth season with the Texans and is in a contract year. Therefore, his future is in the balance after sustaining a season-ending injury against the Cowboys.

The veteran running back began his career with the Miami Dolphins in 2012. During his time in Miami, Miller showcased his versatility out of the backfield. The Miami native would spend four years with the Dolphins; with his best season coming in 2014 when he rushed for 1,099 yards and eight touchdowns.

After testing free agency after the 2015 campaign, Miller decided to take his talents to Texas to play for the Texans. The Texans signed the dynamic rusher to a four-year, $26 million contract ahead of the 2016 season.

In his first season in Houston, Miller galloped for 1,073 yards and five scores. Altogether, Miller has been a mainstay in the Texans offense, missing just four games during his time with the franchise. That's fairly impressive at a position that takes a beating in every game.

Last season alone, Miller was named to the Pro Bowl after garnering 1,136 yards from scrimmage and six touchdowns. With Miller's injury, Duke Johnson and young guys like Buddy Howell and Karan Higdon are expected to see an uptick in their roles.
