He tweeted Sunday night that he plans to return this season.
The injury took place early in the first quarter when Sweat dove to tackle fullback Adam Prentice. Sweat hit Prentice's body with the crown of his helmet. He fell face first on the ground and remained prone as medical staff took the field to tend to him.
Athletic trainers stabilized Sweat on a stretcher then placed him on a cart as his teammates took knees around him on the field. Sweat was able to move his arms and legs as he received medical attention. Fans chanted his name as he left the field.
The Eagles later announced that Sweat had been taken to a hospital for precautionary reasons with a neck injury. They confirmed that he had movement in all of his extremities. They announced Sunday evening that Sweat would be released later in the night and did not provide further updates on his status.
The Eagles lost Sunday's game, 20-10 and enter next week's season finale without having secured the NFC East or the NFC's No. 1 seed.
Sweat, 25, is having a career season after a breakout campaign in 2021 earned his first Pro-Bowl berth. In 15 games, he has 11 sacks, a forced fumble and returned an interception for a touchdown. He's one of four players with nine or more sacks for a 13-3 Eagles team that still retains the NFC's best record despite Sunday's loss.
