Will Power has received medical clearance to race in the IndyCar season finale at Sonoma on September 18 after passing the concussion testing protocol on Tuesday.
Power's hopes of a second IndyCar Series title were dented following a clash with Charlie Kimball in Sunday's race at Watkins Glen, allowing Penske teammate and title rival Simon Pagenaud to extend his points lead.
Power was taken to the medical centre at Watkins Glen following the incident where he was checked and released, but was not cleared to drive again after showing concussion-like symptoms. Power was forced to miss the first race of the season in St. Petersburg for the same reason.
On Tuesday, INDYCAR issued a statement confirming that Power had now been cleared to race after undergoing tests at the University of Miami.
"Verizon IndyCar Series driver Will Power has been cleared to resume driving by Dr. Geoffrey Billows, INDYCAR medical director, after the Team Penske driver successfully passed concussion testing protocol today," the statement reads.
"Power was assessed today at the University of Miami Concussion Center under the supervision of Dr. Stephen Olvey, retired director of the Neuro-Critical Care Unit at Jackson Memorial Hospital in Miami who also served for 25 years as director of medical affairs with Championship Auto Racing Teams.
"During his examination, Power passed both the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) and Vestibular/Ocular-Motor Screening (VOMS) exams."
"Will is doing fine," Dr. Olvey said. "He flew down to the University of Miami Concussion Center early this morning and we conducted two sophisticated tests to determine if he'd suffered a concussion over the weekend, and he passed both of them with no issue whatsoever."
Power will fight with Pagenaud for the title at Sonoma on September 18, knowing he realistically has to win the race to stand any chance of winning the championship.
