NFL lineman BJ Thompson alert and responsive a day after seizure, cardiac arrest

Kansas City defensive lineman B.J. Thompson remained hospitalized but was awake and responsive on Friday, one day after the second-year pro experienced a seizure during a team meeting and went into cardiac arrest at the team's practice facility.

Kansas City trainer Rick Burkholder said the 25-year-old Thompson was placed on a ventilator and heavily sedated Thursday night at the University of Kansas Health System. He was brought out of sedation on Friday and his prognosis is good.

"He's alert. He's a wake. He's coming through quite well," Burkholder said. "We don't have a diagnosis and in medicine sometimes you don't have that. But he's awake and alert and he's headed in the right direction."

Thompson, a fifth-round draft pick out of Stephen F. Austin last year, was in the meeting room before the team was scheduled to have their final voluntary workout of the offseason. He began to have a seizure and kicker Harrison Butker immediately ran to the trainer's room and summoned assistant trainers Julie Frymyer and David Glover.

They were joined by Burkholder in helping Thompson as he went into cardiac arrest. Dr. Jean-Philippe Darche soon arrived from the Kansas Health Sports Medicine and Performance Centre, which adjoins the practice facility.

"Our team of that group of people provided CPR for him,"
