'30 Rock' actor needs kidney transplant

LOS ANGELES, CA Chapman says he's receiving dialysis treatments and will continue to play Grizzwald on the NBC sitcom. He and Kevin Brown, as the character Dot Com, appear as the two-man entourage for a hapless comedian played by Tracy Morgan.

The 35-year-old Chapman is married and has two children. He's scheduled to appear on "The Dr. Oz Show" Tuesday to discuss his health.

Chapman said Monday he was diagnosed a decade ago with high blood pressure and learned two years ago that he was suffering from kidney disease. He gets dialysis treatments three times a week.
