Tracy Morgan underwent a successful kidney transplant recently and will be written out of several episodes of "30 Rock".

The organ donor and the cause of the 42-year-old actor's ailment were not disclosed. Morgan is a diabetic and diabetes is the most common cause of kidney failure.

"Tracy is doing well and taking some much needed time to recover after the surgery," Morgan's spokesperson told OnTheRedCarpet.com. "He is looking forward to going back to work after the holidays."

Morgan, who has three sons with wife Sabina, had the operation around December 10. He is expected to miss filming up to three episodes of "30 Rock" in the spring and his absence on the NBC comedy series will be addressed by making his character appear as though he had a meltdown "because of a good thing that's happened to him," Entertainment Weekly reported.

Grizz Chapman, who plays Morgan's character's sidekick on "30 Rock", also underwent a kidney transplant earlier this year.
