In July 2005, after a 10-year absence from "The Young and the Restless", it was announced that Brown was to reprise the role. At the time, Brown had been appearing on ABC's "One Life to Live" as Paige Miller, and Brown reportedly opted to leave the role when ABC was unable to match the financial terms of a contract offered to her by CBS. She returned on August 5, 2005, and her run ended on January 11, 2006. However, that December, the character returned, though not portrayed by Brown, but by Michelle Stafford, who in addition portrayed Phyllis Summers. For the reason of Brown not returning to the role, the actress said: "I had a bad accident last year, and when they wanted me back in November, I really couldn't go at that time, and that's why I came back looking like somebody else." Stafford only portrayed the role for two months until February 9, 2007, when Sheila was shot by her longtime enemy Lauren Fenmore and presumed dead.
