CBS has announced that the season finales of Survivor: Cook Islands and The Amazing Race 10, the network's two fall reality series, will air on back-to-back Sundays in December.

The Amazing Race 10 will go first and air its one-hour finale on Sunday, December 10 at 8PM ET/PT, the show's regular time period. As usual, The Amazing Race 10's finale will feature the competition's last three teams making their final sprint for the race's finish line.

Survivor: Cook Islands' two-hour finale will air Sunday, December 17 at 8PM ET/PT and be followed by the program's traditional hour-long live reunion special. As he has for the last several years, Survivor host Jeff Probst will host the reunion show, which will take place at the network's CBS Television City studios in Los Angeles. In a departure from Survivor's usual format, Survivor: Cook Islands' finale will begin with five castaways still in the running to win the competition's $1,000,000 prize and "Ultimate Survivor" title.

Survivor: Cook Islands will be the eighth-straight Survivor edition to feature a Sunday evening finale. The last Survivor edition to feature a Thursday evening three-hour finale broadcast was Survivor: Thailand on December 19, 2002.
