LOS ANGELES (thefutoncritic.com) -- NBC's "The Biggest Loser" will head to 9:00/8:00c for the last three weeks of the season, network sources have confirmed to the site exclusively.

In addition, the Peacock will scale back the series to one-hour on Tuesday, April 26 and Tuesday, May 3 to make room for the launch of "The Voice."

The following week (May 10) "Loser" will shift to 9:00/8:00c with "The Voice" now leading off the night at 8:00/7:00c. "Loser" will ultimately wrap its 11th season on May 24 while "The Voice" is currently booked through June 28.

To recap:

Tuesdays (April 26-May 3)
8:00/7:00c - "The Biggest Loser" (One-Hour Episodes)
9:00/8:00c - "The Voice" (Two-Hour Episodes)
