NBC will air one half-hour episode and the 60-minute continuation on the same night during the May sweeps, The Futon Critic confirms.
The season finale of 30 Rock will air in between the two Community episodes.
Moving Community into sweeps week means that Jason Isaacs drama Awake will be partially pushed out of the schedule. Rather than the two-hour finale it was scheduled to have, the series - which has received critical acclaim but disappointing ratings - will now air its final episode on May 24.
Joel McHale recently dropped hints about a fourth season for the show, which has long been considered in danger of cancellation.
Community airs on Thursdays at 8/7c on NBC. In the UK, the series airs on Tuesdays at 10.30pm on Sony Entertainment Television.
