KANSAS CITY, Mo. (WDAF) -- The Kansas City Chiefs canceled practice on Thursday following a medical emergency involving defensive end B.J. Thompson.
Thompson, a second-year defensive end for the Chiefs, was taken to the hospital after suffering a seizure and going into cardiac arrest.
The Chiefs planned to wrap up their voluntary offseason workouts on Thursday, but a team spokesman said the practice would be pushed to Friday. Chiefs coach Andy Reid and other players plan to speak to reporters then.
The 27-year-old Thompson was a fifth-round pick of the Chiefs out of Stephen F. Austin University 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 had no impact on the post-season. Thompson had two tackles in that game.
The Chiefs went on to win the Super Bowl.
