The players on the field felt no effects of Tuesday's earthquake, which measured a magnitude of 5.8. Despite the quake's epicenter originating near Richmond, Va., the shock waves spread throughout the Midwest and along the East Coast.

"We just thought that it was our fans jumping up and down," Acta joked.
