Around December 10, 2010, Tracy Morgan received a kidney transplant. It was announced on December 20, 2010 that he was resting and planning to miss only two episodes of "30 Rock."
Tracy Jamal Morgan (born November 10, 1968) is an American actor and comedian best known for his eight seasons as a cast member on Saturday Night Live and currently known for playing the role of Tracy Jordan on the NBC series 30 Rock.
In 1996, he was diagnosed with diabetes, but says he never took it seriously, refusing to take medication or change his diet. After running a 104-degree fever on the set of 30 Rock, Morgan decided to finally comply with his doctor's orders. He is now very cautious when it comes to the condition. With his consent, many of Morgan's own troubles have been incorporated within episodes of 30 Rock.
