Ohio officials have delayed approving plans for two new racinos.
The Ohio State Racing Commission said the developer's designs for proposed racinos in Dayton and in Austintown, near Youngstown, don't include enough seating for horse race spectators.
The Dayton Daily News reports that race commissioners plan to wait at least a week before deciding to approve the plans, which include slots-like video terminals at both locations.
The developer, Penn National, said adding any more grandstand seating would mean the company would have to re-draw its architectural plans from scratch.
Both racinos are expected to open in spring 2014.
The racing commission must approve Penn National's request to move Raceway Park in Toledo to Dayton and Beluah Park in Grove City to Austintown.
