The Cowboys and Texans shared the Dallas market in competing football leagues in the early 1960s but never settled the matter of supremacy on the field.
They will get a chance this season. The Texans, who in 1963 moved to Kansas City and became the Chiefs, will play the Cowboys at Arrowhead Stadium. The NFL on Monday granted the teams permission to wear their original uniforms and helmets from their inaugural seasons of 1960.
“Personally, that’s something I’m excited about,” Chiefs chairman Clark Hunt said.
“Even though the Cowboys weren’t part of the AFL, their history is linked with that of the AFL and the Chiefs.”
