The defensive end entered NRG Stadium for the team’s game against the Jacksonville Jaguars waving the Texas flag as he received uproarious cheers and deafening applause.
Watt has become an icon for Houston, raising $31million to help rebuild the city in the wake of Hurricane Harvey.
Watt announced the fundraising page with a video on Twitter after Houston’s pre-season game against the New Orleans Saints in late August, with a goal of collecting $200,000.

The football star also worked with his foundation to fill 12 semi-trucks with supplies, which were brought to Houston and distributed in part by Watt and his teammates last week.
For his work, the NFL Player’s Association will contribute $10,000 to Watt’s foundation.
He also became a semifinalist for the Byron Whizzer White Award, given annually by the group to recognize charitable efforts of players.
And although the team lost against the Jaguars, his 99-year-old grandmother displayed her pride.
