At a Hollywood Radio and Television Society luncheon for top show producers on Wednesday, Rescue Me executive producer Peter Tolan told PEOPLE he was making plans to bring her back for the seventh season.
"We are just about finished writing the entire sixth season, which is about 10 episodes, and then there are nine more" for Season 7, he says, "so we know we're going to bring back Maura Tierney, because we loved her and she loved us, which is even more fulfilling."
Those episodes will be shot in the spring of 2010, "so she can take care of herself and come back then."
Tierney's spokesperson confirmed that she indeed "would love to come back to Rescue Me if possible."
After a successful run as nurse Abby Lockhart on the NBC drama ER. Tierney appeared in the fifth season of Rescue Me as Kelly McPhee, a love interest for Denis Leary's firefighter Tommy Gavin. In the season finale that aired in September, Kelly seemed to reject Tommy.
