Houston Texans superstar JJ Watt pledged to pay for funerals of all victims from Friday’s school massacre, the NFL team said.

Shortly after gunfire erupted at Santa Fe High School, Watt tweeted: “Absolutely horrific.”

Watt is renowned for his civic involvement, having led fundraising efforts following Hurricane Harvey. He intended to raise $200,000 but ended up with $37 million.

He won the 2017 Walter Payton Man of the Year award, the NFL’s honor for the player most active in charity work and volunteerism.
