The "medical miss out" meant the daughter of his alleged victim Terry Carter couldn't deliver the statement she was planning to read in open court.
Nekaya Carter said she was set to address Los Angeles County Superior Court Judge Ronald Coen directly and argue her family deserves a "speedy trial" after two years of waiting.
"We just want it to start," she told the Daily News after the short hearing, visibly frustrated.
Knight, 50, has pleaded not guilty to murdering Carter in January 2015.
Prosecutors claim he hit the gas on his Ford F-150 Raptor truck and intentionally mowed down Cle "Bone" Sloan along with Carter in the parking lot of a Compton burger stand — killing Carter.
They claim he was upset with Sloan after a confrontation earlier in the day at a production office for the Dr. Dre-backed movie "Straight Outta Compton."
Knight, meanwhile, claims he was the victim of an armed ambush and feared for his life when he fled the scene and accidentally hit Carter.
The founder of Death Row Records has spent the last two years behind bars, unable to make his $10 million bail.
He's also been plagued by health problems and was back in a hospital last week with "life threatening" blood clots, his fiancée told The News.
"I am worried because Suge is supposed to receive the proper medical care everyone in custody is entitled to," fiancee Toi-Lin Kelly said Wednesday. "Doctors have said Suge's blood clots are life threatening."
She blasted jail officials for allegedly pressuring hospital staff to "return him to jail with only Band-Aid fixes."
"It has been two years of in and out of the hospital, dealing with the same blood clots because the hospital doesn't want to deal with the pressure of the Sheriff's (jail officials) while he is seeking care," she said.
"I am not confident they care about his well-being, if at all," she said.
On Monday, Judge Coen said he learned only a short time before he took the bench that Knight was not going to make it to court.
"This is not the fault of the Sheriff's Department," he said, continuing the hearing to April 6.
Knight's murder trial is tentatively set for late June.
