FILE - BJ Thompson #53 of the Kansas City Chiefs walks off the field during a game against the Arizona Cardinals at State Farm Stadium on August 19, 2023 in Glendale, Arizona.
Kansas City Chiefs defensive end B.J. Thompson suffered a cardiac event on Thursday, prompting the team to cancel all activities for the day, a person familiar with the situation told The Associated Press.
Thompson also reportedly had a seizure, according to multiple reports.
He was taken to the hospital and is in stable condition.
The Chiefs planned to wrap up their voluntary offseason workouts on Thursday, but a team spokesperson said the practice would now be pushed to Friday after Thompson’s medical emergency.
Coach Andy Reid and other players plan to address reporters on Friday.
The 25-year-old Thompson was a fifth-round pick of the Chiefs out of Stephen F. Austin in last year's draft. The only game Thompson appeared in was their regular-season finale against the Los Angeles Chargers, when Kansas City already had clinched its playoff spot and the game's outcome was meaningless. Thompson had two tackles in that game.
