The Brown County School Corporation is receiving less money from the state because of a decline in enrollment.
The new federal guidelines call for more fruits and vegetables in school meals, and require schools only offer fat-free or low-fat milk.
Earlier this month, the project also lost the financial backing of the Bartholomew Consolidated School Corporation.
Mayor Kristen Brown campaigned, in part, on a platform of eliminating the sports complex.
Delays in the project, a pending court case against it and changes in city administration all play into the change of heart.
Leaders of the BCSC say they'll ask for improvements to a school construction plan -- and hope to get more bang for their voter-approved buck.
Because BCSC already offers full-day kindergarten for a fee, it is prepared for legislation calling for full-day kindergarten across the state.
