Grizzwald “Grizz” Chapman, the fan-favorite 30 Rock star who played Grizz on the NBC sitcom for its seven-season run, has died. He was 52.

The actor’s agent Renee Glicker confirmed to Deadline that Chapman died on Friday. Other details, including a cause of death, were not immediately made available.

“We are very sad for his family and friends and for all who knew him and worked with him,” said Glicker. “For all seven feet, 380 lbs of him, he was a very sweet man who loved his family very much. He enjoyed working on 30 Rock every minute. His poor health curtailed his career unfortunately.”

Chapman previously struggled with kidney disease and was a spokesperson for the National Kidney Foundation.

Born April 16, 1974 in Brooklyn, Chapman was known for towering at seven feet tall. He was working as a bouncer at a strip club when he met Tracy Morgan, who cast Chapman and Kevin Brown as his self-referential character Tracy Jordan’s two confidants Grizz and Dot Com in 30 Rock, which ran from 2006 to 2013.

In addition to creating his own YouTube variety series Grizz Chronicles, Chapman appeared in episodes of Blue Bloods, The Blacklist and The Good Fight.
