Power could be forced to sit out IndyCar finale (Update)

UPDATE Despite initially not being cleared to drive following his shunt in today’s Watkins Glen race, Will Power says he feels fine, and expects to be testing at Sonoma on Thursday in preparation for the IndyCar finale.

09/04/16 Will Power's clash with Charlie Kimball on lap 38 of Sunday's Watkins Glen IndyCar race has placed a giant question mark over how the race for the championship will play out on Sept. 18 at Sonoma Raceway.

Diagnosed with concussion-like symptoms by IndyCar's medical staff, the Team Penske driver was released from the infield care center after his hard meeting with the barrier, but was not cleared to drive.
