IndyCar: Mikhail Aleshin medical update

The full extent of injuries suffered by Verizon IndyCar Series driver Mikhail Aleshin was made public early Saturday morning. According to IndyCar, Aleshin has been "diagnosed with fractured ribs, a broken right clavicle, a concussion and chest injuries."

The 27-year-old Russian driver was involved in a frightening crash during night practice on Friday at Auto Club Speedway, and was transported to Loma Linda University Medical Center for a full evaluation. Aleshin is expected to remain at the Southern California hospital until he is able to travel.

Aleshin's crash happened in the short evening practice session that followed Friday's qualifying for Saturday night's season finale. The Schimidt Peterson driver spun at high speed and tangled with Ganassi's Charlie Kimball, sending Aleshin's car into the catch fencing. Marco Andretti then hit wreckage from the incident.

Kimball was checked at the Fontana track's medical centre and cleared to drive in Saturday night's race. His Ganassi team is preparing a spare chassis for him to race.
