The medical emergency happened on what was supposed to be the Chiefs’ final practice of OTAs.

Thompson, 25, reportedly went into cardiac arrest after suffering a seizure during a special teams meeting at the Chiefs’ practice facility. He was quickly attended to by trainers and medical staff before being transported to an area hospital by ambulance. 

Players were reportedly sent home on Thursday. A team’s spokesperson told The Associated Press that the final OTA session was rescheduled for Friday. Head coach Andy Reid is expected to address the situation during Friday’s media availability.
