Crashes have ended the campaigns of New Zealand BMX riders Marc Willers and Sarah Walker at the supercross world cup in Norway.
Willers spilled out of contention during his quarterfinal while Walker has dislocated her shoulder after she crashed in the final at Randaberg.
Walker will fly home for a MRI scan to determine if any greater damage has been done to the shoulder.
Fellow New Zealand olympic hopeful, Kurt Pickard, has also flown home after injurying his wrist in a crash on the opening day.
