It's a NFL week at the ranch, and the competition to be the Biggest Loser of the week is fiercer than ever with the weigh-in winner getting an amazing prize -- a VIP trip for two to the Super Bowl! Host Alison Sweeney reminds the contestants that if they want to be the best, they have to beat the best at a football throwing challenge in which they compete alongside Green Bay Packers linebacker Clay Matthews, New Orleans Saints quarterback Drew Brees and Atlanta Falcons tight end Tony Gonzalez. One player really struggles emotionally this week, while another remains determined despite being partially sidelined with an injury. There's a grueling, calorie-burning competition among the three teams led by trainers Bob Harper, Anna Kournikova and Dolvett Quince. And later, Denver Broncos quarterback Tim Tebow, Buffalo Bills linebacker Shawne Merriman and Hall of Famer Eric Dickerson help put the contestants through last chance workouts they'll never forget before a tense weigh-in reveals which player gets the coveted Super Bowl tickets.

In this inspiring Thanksgiving special unlike any before on "The Biggest Loser," viewers can catch up with some of their favorite contestants ever, but they'll also be treated to never-before-seen footage and -- for the first time ever -- hilarious bloopers featuring the trainers, host Alison Sweeney and the contestants. And trainers Bob Harper, Anna Kournikova and Dolvett Quince will all be on hand to share their thoughts about the current season of the show. Fan favorites like Abby Rike, Tara Costa, O'Neal Hampton and season five winner Ali Vincent will reveal what they're up to now, along with season eight champ Danny Cahill, season 11 winner Olivia Ward, and other popular players. One contestant makes a big surprise announcement, and cameras will also follow trainer Bob Harper through "a day in the life." Plus, cooking expert Aida Mollenkamp will prepare a healthy Thanksgiving feast for the trainers and past season contestants, and share great cooking tips as well. Alison Sweeney hosts the special.

This week, the contestants are surprised by three special guests -- past season contestants Hannah Curlee, Adam Hurtado and Marci Crozier, who each visit and inspire the team that represents his or her respective age group. Then all the players are off to a wild weather challenge in which they have to race while battling the elements -- including wind, rain and snow -- to win coveted letters from home. The winning team receives an unexpected and very emotional bonus prize. Later, trainer Bob Harper takes his team to the pool for last chance workouts, where one player tries to overcome his fear of the water, while trainer Dolvett Quince pushes his team to new heights in the gym and trainer Anna Kournikova takes her team to a favorite spot -- the new "Biggest Loser" tennis court. In the end, the losing team at this week's weigh-in must decide who will be going home. Alison Sweeney hosts the series.

This week, the contestants learn that the gym will only be open three times a day, and each team will only have one two-hour time slot daily to work out. A donut temptation will help determine which team gets what slot, and then players have to learn to squeeze in their daily workouts just like in real life. Dr. Huizenga meets with contestants and their trainers for some sobering news about their medical conditions, and one player is shocked to learn what his real inner age is -- and that he is the sickest person at the ranch. Then all the teams use their weight to move a ball through a maze over water in a wild challenge that proves to be way harder than it looks. Later, another player is sent home after the weigh-in yields a very surprising number for one contestant. Host Alison Sweeney stars along with trainers Bob Harper, Anna Kournikova and Dolvett Quince.

In this must-see, exciting live finale, the contestants from this season return for a special reunion and a chance to weigh in one last time - and show America how much weight they've all lost since beginning their weight-loss journeys. Those who have been eliminated will compete for the $100,000 "at home" prize. Then it's the moment viewers have been waiting for, when one of the three finalists will be named this season's "Biggest Loser" and win the coveted grand prize of $250,000! Alison Sweeney hosts the series, and trainers Bob Harper, Anna Kournikova and Dolvett Quince also star.
