While no decision has been finalized, ABC is said to be eyeing one final season for the “Grey’s Anatomy” spin-off “Private Practice.” The network moved the series to Tuesday nights, and after a disappointing Tuesday premiere, the show was up 29 percent from the previous week. “Practice” star Kate Walsh, who’s contract is up at the end of this season, has apparently agreed to do 13 more episodes of the show, giving the drama a shorter season order.
