‘30 Rock’ Star Dies in His Sleep at 52

He had battled kidney disease for years.

Grizz Chapman, the seven-foot star of NBC sitcom ‘30 Rock,’ has died in his sleep. The Brooklyn-born performer, 52, played Tracy Morgan’s hulking bodyguard Grizz Griswold across all seven seasons of the Emmy-winning comedy. He had fought kidney disease for years and underwent a transplant in 2010, later becoming a National Kidney Foundation spokesman. Griswold’s agent, Renee Glicker, told Deadline he had died on Friday and that no cause has been released. “For all seven feet, 380 lbs of him, he was a very sweet man who loved his family very much,” she said. Co-star Kevin Brown, who played fellow bodyguard Dot Com, wrote on Facebook: “I regret to inform you that Mack Chapman aka Grizz Chapman passed today.”
