The Texans defense suffered a devastating blow early in the Sunday Night Football game against the Kansas City Chiefs.
On the opening drive, injured his leg on a Chiefs pass play and did not return. While Watt did walk off the field with assistance, he was then immediately evaluated in a tent on the sideline before being carted to the locker room. The three-time AP Defensive Player of the Year left NRG Stadium in an ambulance to be further examined at the hospital.
The team later confirmed that Watt had suffered a tibial plateau fracture to his left leg.
