NASCAR says three pit road crew members have been taken to a hospital after a fire broke out on pit road at Richmond International Raceway.

Two of the crew members were working in Brendan Gaughan's pit, where the fire erupted, and one was in Eric McClure's pit.

There was no additional information about the extent of their injuries, or what sparked the fire.

Television replays showed a huge ball of flame that appeared to engulf at least one crew member in Gaughan's pit. The man got a lot of attention from fellow crew members, who quickly doused any flames. The man appeared to walk away.
