Cushing is out for the season with a torn anterior cruciate ligament, coach Gary Kubiak announced today.
The Texans suffered a major blow with Cushing now sidelined for the remainder of the season.
The former USC standout will be placed on injured reserve.
Cushing will have surgery to repair the damage in two to three weeks after the swelling subsides.
"Big blow to our team," Kubia told Houston reporters. "You feel bad for Brian because he works so hard and was playing so well."
Cushing was a second-team All-Pro selection last season.
