Then they head to the final weigh-in, where two of the final four players fall below the yellow line. But instead of them choosing which of the players will be a finalist for the finale, Sweeney tells them about one last game-changing twist - that for the first time ever in "Biggest Loser" history, America will determine who the third finalist will be. Viewers will vote online at www.nbc.com on the two that fall below the yellow line, with voting taking place for 48 hours following the end of the east coast broadcast at 10 p.m. ET on April 8. Who America chooses to be a finalist - and who they choose to eliminate - will be revealed in the first five minutes of the live finale on April 15.
