A dictionary says plough means to form furrows with a plow, so I thought those who got ploughed in sports had deep cuts. However, my understanding might be a little strange in the following context (Harry Potter 4 [US Version]: p.108) , because he hit the ground. What kind and degree of injury did he get when he got ploughed? Would you use ‘get ploughed’ in common sports, I mean, non-magical sports?
(The sport’s players are flying on their brooms. Two of them are diving for a small ball.)
at the very last second, Viktor Krum pulled out of the dive and spiraled off. Lynch, however, hit the ground with a dull thud that could be heard throughout the stadium. A huge groan rose from the Irish seats.
(Then a spectator, Charlie, says)
”He’ll be okay, he only got ploughed!” Charlie said reassuringly to Ginny, who was hanging over the side of the box, looking horror-struck. [bold font is mine]
Side Note: I think ‘only’ means that it’s easy to recover by magic. So I guess ‘get ploughed’ causes serious injury in our world.
