Achilles injury, was jumping up and down and when he took off you could see something happen. He is they guy who covered Kelce. Kelce did nothing with him in but then took off when he went out.
Right when it happened I immediately thought achilles, calf, or maybe lower hammy.
Reminds me of those baseball injuries you hear about. Like when John Smoltz burned himself as he tried ironing his shirt while wearing it. There have actually been quite a few celebratory injuries but can't think of any offhand.
