TNT’s drama series “Saving Grace” is planning to end next summer with a nine-episode final season to air in 2010.

TNT offered Fox TV Studios, Saving Grace’s producer, a full fourth season pickup, but the studio declined, citing financial reasons (most likely star Holly Hunter’s paycheck!).

TNT programming chief Michael Wright commented, “It’s been a fantastic beacon for the network, which has both challenged and entertained viewers in ways few other shows on television ever dare.”

Saving Grace’s third season finale will air on Tuesday.
