Scott Redding escaped serious injury during a huge crash in Sunday's Moto2 race at Misano, but was left devastated by the news that Shoya Tomizawa sustained fatal injuries in the incident.
Tomizawa fell from fourth place after running wide onto the back straight and was hit at high-speed by Alex de Angelis and then Redding, who were close behind and had no chance to avoid the stricken rider.
19-year-old Tomizawa died later in hospital.
Redding was also taken to the circuit medical centre, where he received ten stitches for a laceration to his back. de Angelis miraculously walked away from the huge accident.
"Scott's crash was a big one, so we are thankful that the only injury he sustained was a minor laceration on his back," said Redding's Marc VDS team manager Michael Bartholemy.
"We were deeply saddened by the news that Shoya Tomizawa succumbed to the injuries sustained. He was a respected rival and will be sorely missed in the paddock.
"Like everyone in the Marc VDS Racing Team, my thoughts are with his family and friends at this time."
