Houston Texans -- Our Stadium Weathered the Storm

Good news for the Houston Texans ... the team's $350 million stadium has suffered NO DAMAGE from the brutal floods wreaking havoc on the area ... TMZ Sports has learned.

We talked with a spokesperson for NRG Park who tells us, "We're pretty lucky. No damage on the property at all."

"We span across 350-acres and our property includes NRG Stadium (home to the NFL's Houston Texans), NRG Center, NRG Arena and NRG Astrodome."

"Most of the damage was on the freeways surrounding us and, of course, the streets. We had to cancel work yesterday because no one could get around."

One more interesting note ... the spokesperson adds, "Our roof is retractable, so during the storm it was closed. Hence, why there was no water collection."

We also spoke with a rep for the Houston Astros -- who told us Minute Maid Park was also spared ... suffering no major damage on the 29 acre property.
