The Romanian website ProSport describes what you're watching this way: "One of the local players need medical care, so he was taken off the field with wheelbarrow! It is motorized wheelbarrow, a patented invention by a villager Urseni." I love how A. Those two sentences wouldn't be out of place in a Borat deleted scene, and B. It's never explained why the motorized wheelbarrow was actually invented. I mean, why is that kind of genius hiding in Romanian villages?
