An MRI has confirmed that Houston Texans running back Lamar Miller has a torn ACL and will miss the upcoming season, a source told ESPN's Adam Schefter.
Miller suffered the injury during Saturday night's preseason game against the Dallas Cowboys. He was taken off the field on a cart during the first quarter in Arlington, Texas.
On first down, Miller was tackled by Cowboys tackle Maliek Collins, who hit him just above the left knee. Miller, 28, grabbed his left leg and was checked out by the medical staff.
