Donald Glover, Tracy Morgan

Is Tracy Morgan getting replaced on 30 Rock?

Community star and internet sensation Donald Glover will guest-star on the NBC sitcom's upcoming live episode, TVLine reports. But Glover isn't just playing anyone. He's playing a younger version of TGS star Tracy Jordan (Morgan) on the April 26 episode, executive producer Robert Carlock tells the site. "Donald does an excellent Tracy Morgan-slash-Jordan impression."

Carlock tells TVLine that the live episode will feature many new flashbacks to old TGS shows when Kenneth (Jack McBrayer) must prove to Kabletown, as well as Jack (Alec Baldwin) and Liz (Tina Fey), that live television is worth doing and that TGS should not switched to a pre-taped format.

Glover's gig marks a homecoming for the comedian, who wrote for 30 Rock for three years and appeared in several blink-and-you-missed-it cameos before he moved onto acting — and Community — in 2009.
