MADISON, Wis. — Houston Texans defensive end J.J. Watt has donated $10,000 to help the family of a Wisconsin firefighter killed in an explosion.

A natural gas leak in downtown Sun Prairie led to an explosion Tuesday evening that claimed the life of Sun Prairie Fire Department Capt. Cory Barr. He leaves behind a wife and 3-year-old twin daughters.

Kate Cichy, a spokeswoman for GoFundMe, said in a news release Wednesday evening that Watt has donated $10,000 to the GoFundMe for Barr's family. She added that the Sun Prairie community has already raised nearly $70,000 for the family.

Watt was born in Waukesha, Wisconsin, and played college football at Wisconsin. He has been selected to four NFL Pro Bowls.
