The 20-year-old New South Wales man was in an induced coma after falling head first in Invernell, Channel 9 news reported.
The fad took off when rugby league star David “Wolfman” Williams — a renowned planker — showed off his skills on live television after a try in March, lying stretched out on the ground. The scene has been taken up by YouTube, where it has gotten nearly 100,000 views.
“People are trying to out-do each other by planking on structures or in precarious positions, putting themselves and others at risk,” said Queensland police in a statement. (/AFP/Getty Images)
