Lauren Graham (Gilmore Girls) will join the cast of NBC’s Parenthood, in the role vacated by Maura Tierney.
Tierney was forced to drop out of the dramedy to undergo treatment for breast cancer.
Her illness caused the series to be delayed. It will now be held off until after the Winter Olympics.
Graham will play the character portrayed by Dianne Wiest in the original Ron Howard film. Helen Hunt’s name had also been floated as a possibility.
Howard is an executive producer on the NBC series.
