Philadelphia Eagles quarterback Jalen Hurts will miss the remainder of the 2026 NFL season after further medical testing revealed multiple blood clots in his lungs, the team and his agent announced Monday. The diagnosis is more serious than the superficial blood clot initially discovered in his left calf before Philadelphia's game in London against the Jacksonville Jaguars on October 11.

The Eagles said Hurts has now been diagnosed with deep vein thrombosis, a condition involving a blood clot in a deep vein, as well as bilateral pulmonary emboli, meaning blood clots are present in both lungs. His treatment will involve anticoagulants, commonly known as blood thinners, which prevent clots from growing and reduce the risk of additional clots. He will be prohibited from participating in contact activities, including football, while undergoing treatment.

"He is clinically stable and has no significant functional limitations," the Eagles and Hurts' agent, Nicole Lynn, said in a joint statement. "Jalen's prognosis is very good, and we expect a full recovery." The statement added that the team anticipates he will suffer no long-term effects and will remain involved with the team and continue conditioning while recovering.

The medical issue first emerged after Hurts reported calf discomfort following Philadelphia's October 4 game against the Los Angeles Rams, when he said he had been cleated in the leg. An ultrasound performed in London on October 10 revealed a superficial blood clot. After consulting with medical staff and doctors, the Eagles said they determined Hurts could safely play, while recommending another ultrasound within 72 hours.

Hurts subsequently started against Jacksonville and completed 21 of 40 passes for 220 yards and one touchdown in Philadelphia's 19-17 loss. The team said a follow-up ultrasound on October 15 showed movement in the clot, prompting further medical evaluations and eventually the more serious diagnosis.

Reports say Hurts was advised not to sleep and stayed awake for about 36 hours before the London game. That detail has raised questions about the circumstances surrounding his preparation and availability, although the Eagles' public statements have not independently confirmed that specific account.

The Eagles placed Hurts on injured reserve on October 17. Reports indicate he could require roughly three months of recovery, making a return this season unlikely. Backup quarterback Tanner McKee started in his place during Sunday's 25-14 loss to the Carolina Panthers, as Philadelphia fell to 2-4.

Hurts, 28, was the Eagles' starting quarterback for their first five games of the season and entered the year as one of the franchise's most important players after leading Philadelphia to a Super Bowl LIX victory and earning the game's Most Valuable Player award. He had thrown eight touchdowns against three interceptions in five starts this season.

The team says the outlook for Hurts' recovery is positive, but his absence leaves Philadelphia without its starting quarterback as it attempts to turn around a difficult start to the season. His return to contact football will depend on his medical progress and when doctors determine he can safely stop taking blood thinners.
