WorldSSP Champion Dominique Aegerter has been ruled out of the remainder of the round six action at Most due to concussion.

The Ten Kate Yamaha was collected in the first corner melee of Saturday’s race one with the Swiss rider seen needing assistance to get to his feet in the aftermath. After checks at the Autodrom Most medical centre, Aegerter was cleared of any serious injuries but ruled out of the running due to suffering from concussion.

With the winner of the past nine races out of action, Evan Bros. rival Lorenzo Baldassarri romped home to a six-second victory in the opening race, cutting the deficit in the championship standings to just 39 points, with another uncontested 25 up for grabs on Sunday.
