U.S. soccer journalist Grant Wahl dies at World Cup match in Qatar

Grant Wahl, one of the most well-known soccer writers in the United States, died early Saturday while covering the World Cup match between Argentina and the Netherlands in Lusail, Qatar.

U.S. media seated near him said Wahl fell back in his seat in a section of Lusail Iconic Stadium reserved for journalists during extra time of the game, and reporters adjacent to him called for assistance. Emergency services workers responded very quickly, the reporters said, and the reporters later were told that Wahl had died.

"He received immediate emergency medical treatment on site, which continued as he was transferred by ambulance to Hamad General Hospital," the World Cup organizing committee said in a statement, which did not list a cause of death. "We are in touch with the US Embassy and relevant local authorities to ensure the process of repatriating the body is in accordance with the family's wishes."

Wahl tweeted on Wednesday that he had celebrated his birthday that day. American reporters who knew Wahl said he was 49.

"We could always count on Grant to deliver insightful and entertaining stories about our game, and its major protagonists," the U.S. Soccer Federation said in a statement. "Grant's belief in the power of the game to advance human rights was, and will remain, an inspiration to all. Grant made soccer his life's work, and we are devastated that he and his brilliant writing will no longer be with us."

Wahl was covering his eighth World Cup. He wrote Monday on his website that he had visited a medical clinic while in Qatar.

"My body finally broke down on me. Three weeks of little sleep, high stress and lots of work can do that to you," Wahl wrote. "What had been a cold over the last 10 days turned into something more severe on the night of the USA-Netherlands game, and I could feel my upper chest take on a new level of pressure and discomfort."

"I went into the medical clinic at the main media centre today, and they said I probably have bronchitis. They gave me a course of antibiotics and some heavy-duty cough syrup, and I'm already feeling a bit better just a few hours later. But still: No bueno," he wrote.

Wahl wore a rainbow T-shirt in support of LGBTQ rights to the United States' World Cup opener against Wales on Nov. 21 and wrote that security refused him entry and told him to remove the shirt. Gay and lesbian sex is criminalized in Qatar, a conservative Muslim emirate.

Wahl wrote he was detained for 25 minutes at Ahmed Bin Ali stadium in Al Rayyan, then was let go by a security commander. Wahl said FIFA apologized to him.

U.S. State Department spokesman Ned Price tweeted late Friday: "We were deeply saddened to learn of the death of Grant Wahl and send our condolences to his family, with whom we have been in close communication. We are engaged with senior Qatari officials to see to it that his family's wishes are fulfilled as expeditiously as possible."

Wahl is survived by his wife, Dr. Celine Gounder, an associate professor at New York University School of Medicine, attending physician at Bellevue Hospital Centre and CBS News contributor.

Gounder tweeted that she was thankful for the support of her husband's "soccer family" and friends who had reached out.

"I'm in complete shock," she wrote.
