A source told FOXSports.com that it's believed Lawler suffered a stroke or heart attack, with the former being the most likely. The fact medical personnel were at ringside allowed Lawler to receive immediate treatment, the source said.

There has yet to be an update from WWE since Michael Cole gave his final address before Raw went off the air and official word likely won't come down for some time as tests are still being done at a local hospital in Montreal, Quebec, Canada, where the show was being held.
