For Houstonians in the know game day question

Shouldn't the Metrorail be in operation from South Fannin St. Station to Reliant Park Station the afternoon of opener (30th)? The online trip planner only shows bus operating route when completing the form; that rail station has a park and ride and shows the rail on other days just 1 minute direct trip while the bus is a roundabout longer trip. Am I missing something, since it usually shows all available routes?
TIA
