HOUSTON — Commissioner Roger Goodell of the N.F.L. declined to take a public stance last week on President Trump’s executive order temporarily banning visits by citizens from seven predominantly Muslim countries, even as leaders in the N.B.A. spoke out against the order.

But the owner Shahid Khan of the Jacksonville Jaguars made it clear Saturday that he was opposed to the ban and said he had been heartened on Friday when a federal judge in Seattle temporarily blocked the president’s immigration order.

“The bedrock of this country are immigration and really a great separation between church and state,” Mr. Khan, 66, said in Houston, the site of Sunday’s Super Bowl.

“Even for the country, it’s not good,” he added, explaining that he thought the order could deny entry to some of “the tens of thousands of people who can contribute to the making of America.”
