Dallas Mavericks head coach Rick Carlisle collapsed during this afternoon's practice, and subsequently removed from the floor via stretcher and hospitalized, mere hours before his team was scheduled to travel for Saturday's preseason game against the Phoenix Suns, reports Eddie Sefko of the Dallas Morning News:
It was unknown specifically what happened to Carlisle, who was sitting up on the stretcher when he was wheeled toward the loading dock at about 12:38 p.m. An ambulance was waiting. At 12:50 p.m., the ambulance left the loading dock.
It's a scary situation for the 50-year-old Carlisle and the Mavericks, though he seems to have stabilized:
Carlisle was resting comfortably, but will not accompany the team to Indian Wells, Calif., this afternoon, where the Mavericks play Phoenix on Saturday night.
As he was taken out of the arena, Carlisle was moving his arms and was alert.
We'll update this stream as more information about his condition becomes available.
