PENSACOLA - A planned kidney transplant that won two Mississippi sisters their freedom from prison can't take place until one quits smoking and they lose a combined 160 pounds.

Jamie and Gladys Scott had served 16 years of their life sentences for a robbery when they were released on Jan. 7. They moved to Pensacola, Fla.

Mississippi Gov. Haley Barbour set a condition of release that Gladys Scott give a kidney to Jamie, who suffers from kidney failure. Gladys had volunteered to do so.

Jamie Scott said Wednesday that a doctor said she has to lose 100 pounds for the operation. She said Gladys must lose 60 pounds and stop smoking.

Barbour hasn't said whether he'll send the sisters back to prison if the transplant doesn't happen.
