Texans defensive end J.J. Watt has already raised more than $3.2 million on his YouCaring.com page for Houston flood relief and has raised the goal to $4 million to help those affected by Hurricane Harvey.

He started with a goal of $350,000 and has continued to raise the goal each time he reached one.

Watt wrote Monday that Houston Rockets point guard Chris Paul's $50,000 donation put the fund over the $500,000 mark. The Rockets also announced that owner Leslie Alexander has contributed $4 million to mayor Sylvester Turner's relief fund. Alexander then revised that figure to $10 million

The Houston Texans and owner Bob McNair will donate $1 million — which will be matched by the NFL Foundation — to the United Way of Greater Houston's flood relief fund.

"These dollars will be put to go use in the relief and recovery efforts," Texans coach Bill O'Brien told reporters Monday at The Star in Frisco, Texas, the Dallas Cowboys' facility where the Texans are working out.

"We also hope our actions will encourage others to do whatever they can to help their neighbors in need right now."

Cowboys executive vice president Charlotte Jones Anderson announced that the team will hold a telethon to raise money as well.

New England Patriots owner Bob Kraft said Monday that his family will match all funds donated to the American Red Cross in support of Hurricane Harvey disaster relief up to $1 million.

“The New England Patriots and our fans have celebrated two of our franchise’s greatest and most memorable moments in Houston," Kraft said in a statement. "The city was a tremendous host for Super Bowl XXXVIII in 2004 and once again this past February for Super Bowl LI. Houston could not have provided more support to us during those visits, and we welcome the opportunity to provide this support when Houston needs it most."
