It happened earlier in the summer at the Sachsenring when a mechanic for team AB Cardion Ducati crossed pit lane without looking, right onto the path of Aprilia rider Mattia Pasini.
Pasini ended up banging his head hard on the pavement and in the hospital for a check up. The mechanic was ok but the bike almost ended up inside Rossi's pit box. Amazingly Pasini was allowed to race though obviously concussed and confused after the fall.
Japanese 250 rider Nobuyuki Wakai died in similar accident in 1993 when he collided with a unauthorized spectator in the Jerez pit lane
