Verizon IndyCar veteran Will Power has been cleared to resume driving by series medical director Dr Geoffrey Billows, after the Team Penske driver successfully passed concussion testing protocol today.

Power was assessed at the University of Miami Concussion Centre 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 Centre 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 was involved in a racing incident on lap 39 of Sunday's IndyCar Grand Prix at The Glen presented by Hitachi, when his #12 Verizon Team Penske Chevrolet made contact with another car and veered into the barrier alongside the track.

The doctors' decision is good news for Power's championship bid, as it means he is still in the two-way fight with Penske team-mate Simon Pagenaud, whom he trails by 43 points with one race remaining in the season, the GoPro Grand Prix of Sonoma on 18 September.
