Jalen Hurts will miss the rest of the season after doctors discovered multiple blood clots in the Philadelphia Eagles quarterback's lungs, Action News' Ducis Rodgers confirmed on Monday.
Hurts will undergo treatment for the blood clots that will take at least three months, according to NFL Network's Ian Rapoport.
He was initially diagnosed with a left calf superficial vein thrombosis by a specialist in London, according to the team. However, after further testing and monitoring, the team said his condition has been upgraded to a deep vein thrombosis, as well as bilateral pulmonary emboli.
"He is currently stable and has no significant functional limitations," the team said on social media.
Rapoport reported, "Before the London game, Hurts was in the hospital until 4 am and did not sleep because sleep was a risk," adding that he played that game "without having slept."
The Eagles lost that game against the Jacksonville Jaguars 19-17.
Eagles coach Nick Sirianni was the only member of the organization made available to the media on Monday — not general manager Howie Roseman or any member of the team's medical staff — and largely deflected questions about Hurts' health or how the team handled the situation.
"I'm not a medical expert," Sirianni said. "I lean on our guys in all those situations. I'm a football coach. I lean on our medical experts in every situation. I have full trust and full faith in them. It's not just me that has major care for our players. It's them, as well."

Sirianni declined to say Monday why the Eagles allowed Hurts to fly home with a blood clot. He referred to statements the Eagles and Hurts' agent released over the last week that addressed the timeline of his injury and treatment.
He had no answers on specific questions about Hurts and his blood clots.
"I understand you want this information on this," Sirianni said. "I fully trust the people that are involved in helping us all make these decisions. We have great people here."
Hurts hadn't missed more than two games in a season since becoming the full-time starter in 2021. He has led the Eagles to five straight playoff appearances, three NFC East titles and two Super Bowl appearances, beating the Chiefs 40-22 two years ago.

Tanner McKee started for Hurts against the Panthers. McKee finished 26 of 45 for 215 yards and a touchdown in the 25-14 loss. The Eagles (2-4) have lost four consecutive games for the first time since 2020.
Sirianni added that beleaguered offensive coordinator Sean Mannion was still the play-caller.
Hurts has eight touchdown passes and three interceptions with 933 yards passing this season. He is in the middle of a five-year, $255 million extension, including $179.3 million guaranteed, that takes him through the 2028 season.
The Eagles stunned fans when they drafted Hurts out of Oklahoma in the second round in 2020. They seemingly had Carson Wentz entrenched at QB and had more pressing needs. But Hurts supplanted Wentz and became one of the top quarterbacks in the NFL.
"I haven't been without Jalen for an extended period of time," Sirianni said. "I have the utmost confidence in Tanner. But I miss him. I know that will be the case. Jalen and I have been together, head coach and quarterback, for six years."
Deep vein thrombosis (DVT) is a blood clot that forms in a vein deep in the body, usually the lower leg or thigh, according to the National Library of Medicine.
Bilateral pulmonary emboli (PE) means there are also blood clots in both his right and left lungs. A PE typically occurs when a blood clot breaks loose and travels through the bloodstream to the lungs.
Health experts say a pulmonary embolism can be serious, potentially causing permanent damage to the lung, low oxygen levels in the blood, and damage to other organs in your body from not getting enough oxygen.
His treatment is expected to include anticoagulation -- or blood thinners -- and he is not allowed to participate in any contact activities, team officials said.

People can make a full recovery when a pulmonary embolism is spotted and treated early, health experts say.
"Jalen's prognosis is very good, and we expect a full recovery," the team said on social media. "We anticipate that he will have the opportunity to resume contact football activities when off the blood thinners. In the meantime, he will remain active around the team and continue to condition."
The team also said, "We anticipate that he will have no long-term effects."
