The Biggest Loser : Season 9 Episode 5

This week, contestants are surprised by the return of the blue and yellow teams, who were sent home after the first challenge of the season. Now they’re back, 30 days later, to weigh in and try to earn a spot back on the ranch. Then a vigorous football challenge tests everyone’s stamina, except for one player sidelined with medical issues, and provides immunity for the winner – but a big disadvantage for the losing team. Later, after another elimination round sends a player home, host Alison Sweeney surprises the contestants with exciting news.
