Philadelphia Eagles quarterback Jalen Hurts has been diagnosed with blood clots in both lungs and will be sidelined for the remainder of the NFL season, the team and Hurts’s agent announced Monday. The 28-year-old’s condition, identified as deep vein thrombosis along with bilateral pulmonary emboli, requires treatment with blood thinners, precluding him from playing during that period.

Hurts initially received a diagnosis of left calf superficial vein thrombosis on October 10, ahead of the Eagles’ game in London against the Jacksonville Jaguars, a match in which he still participated. Subsequent medical evaluations, including an ultrasound on Wednesday, revealed mobility within the clot, prompting Hurts to miss Sunday’s 25-14 loss to the Carolina Panthers.

The Eagles and Hurts’s representative Nicole Lynn confirmed the update Monday morning. The quarterback is expected to continue treatment involving only blood thinners and plans to remain with the team to focus on conditioning while sidelined. No further complications have been reported.

Prior to the diagnosis, Hurts had accumulated 933 passing yards, eight touchdowns, and three interceptions over five games. The former Super Bowl MVP has demonstrated durability in his career, having played at least 15 games in each of his first six NFL seasons.

With Hurts out, Tanner McKee has stepped in as the starting quarterback. Additional depth at the position includes Cole Payton and Joe Milton. The Eagles have struggled lately, entering the upcoming Monday Night Football game against the Dallas Cowboys with a four-game losing streak and a 2-4 record.
