Maura TierneyMaura Tierney is on her way to a speedy recovery.

The actress, who last year was forced to drop out of the NBC drama 'Parenthood' to undergo treatment for breast cancer, will reprise her role as Kelly McPhee on 'Rescue Me,' according to an exclusive report from TV Guide.

But don't get too excited: While Tierney has already filmed some of her scenes, executive producer and star Denis Leary told TV Guide that her arc will be delayed until the show's seventh and final season, in -- wait for it -- 2011.

The show is currently filming its final 19 episodes, which will be divided into two seasons. The final season is set to coincide with the 10th anniversary of the terrorist attacks on Sept. 11.
