A visibly distraught Cole later updated television viewers about what had happened. After a couple more updates, the show continued without commentary until its conclusion.
Lawler, who still wrestles occasionally, had competed in a match earlier in the show, about 45 minutes before his heart attack.
In the video above, you can see people working on Lawler, then carrying him to a waiting stretcher.
The WWE released the following statement early Tuesday morning:
"Jerry "The King" Lawler suffered a heart attack while commentating during last night’s broadcast of Monday Night Raw in Montreal. We are hopeful Jerry makes a full recovery and returns to WWE in the near future. Our thoughts are with Jerry and his family."
Lawler is a veteran "Raw" announcer who has had a 40-plus year career as a pro wrestler. He perhaps is best known for his famous run-in with comedian Andy Kaufman on "Late Night with David Letterman," when Lawler slapped Kaufman in a scripted incident to help promote an upcoming match between the two.
