Chloe Kim’s Olympic three-peat bid in doubt after dislocated shoulder

• Kim, 25, injured shoulder during training in Laax

• MRI will determine Olympic availability for US star

• Two-time champion chasing historic third gold

Chloe Kim's pursuit of an unprecedented third straight Olympic gold medal has been thrown into uncertainty after the American snowboard star dislocated her shoulder during a training session in Switzerland.

Kim, the dominant force in women's halfpipe snowboarding for nearly a decade, revealed the injury on Thursday, sharing video of the fall that caused the scare. The injury occured while Kim was training in Laax, a regular World Cup venue and a key pre-Olympic stop on the circuit. The 25-year-old landed a maneuver cleanly but lost her edge shortly afterward, sliding awkwardly across the pipe and into the wall.
