Comedians Morgan, Harris Stanton and Ardie Fuqua were hospitalized after the Mercedes limousine bus they were passengers on was hit by a tractor trailer on the New Jersey turnpike in June 2014. James McNair died of injuries sustained in the accident, while Morgan was left in critical condition.

In 1996, Morgan was diagnosed with diabetes and for years has struggled with alcohol abuse. Morgan has conceded that many of his own troubles were incorporated within 30 Rock episodes. In early December 2010, Morgan received a kidney transplant necessitated by his diabetes and alcohol abuse.
