The Philadelphia Eagles ruled quarterback Jalen Hurts out of their Sunday game against the Carolina Panthers after a follow-up ultrasound showed movement in a superficial blood clot in his calf, the team said Thursday. Philadelphia said it was determining an appropriate course of treatment and described Hurts’ health and safety as its priority.

The team’s account traced the issue to a hit during Philadelphia’s Oct. 4 game against the Los Angeles Rams. Hurts told medical staff on Oct. 8 that he had been cleated during that game and sought calf treatment after practice. The Eagles said he had practiced in full on both Wednesday and Thursday before requesting care, and that he received treatment and practiced in full the next day.

After the team traveled to London, an ultrasound on Saturday found the superficial clot, according to the Eagles. The team said its medical staff and doctors in London reviewed the results and concluded that activity and mobility were important and that Hurts could safely play. They recommended another ultrasound within 72 hours of the game and the return trip to Philadelphia.

Hurts played in Sunday’s game without limitation, the team said. He received treatment Monday and Tuesday and practiced in full Wednesday, according to Philadelphia’s statement. The follow-up scan Wednesday night showed movement in the clot, prompting the decision to keep him out against Carolina. The Eagles said they had communicated with the league office about the matter while the team was in London and after returning.

The team did not provide a timetable for Hurts’ return or specify what treatment he would receive. His status for games after Sunday therefore remained unresolved in the information released. Philadelphia’s schedule following the Panthers game includes consecutive matchups against its division rivals Dallas, Washington and the New York Giants.

Tanner McKee, identified in the source report as the Eagles’ backup quarterback, was in line to start against Carolina. The report said McKee had made two career starts, with Philadelphia winning one and losing one.

The Eagles’ announcement followed the sequence of an initial calf complaint, treatment and practice, an ultrasound that detected the clot, Hurts’ participation in the London game, and a later scan that found movement. The club’s public statement provided the medical timeline and its decision to rule him out, but did not offer further details about the clot or the expected length of his absence.
