After Cowboys wide receiver CeeDee Lamb lost a would-be touchdown in the sun last week, Cowboys owner Jerry Jones was defiant when asked about using curtains for NFL games. He went as far as to joke about tearing down the stadium.

The team said no one was injured in the incident, which occurred a few hours ahead of Monday night’s game against the Texans.
