Speaking to British weekly newspaper Motorsport News, Button said: “There was a possibility of me racing next year  in IndyCar, it just didn’t come about because of COVID.
“I was supposed to do a couple of tests with Arrows McLaren SP.
“First one I couldn’t do because of COVID, it was cancelled, and the second one was between the two Austrian GPs.
“So I missed out on doing that which is a shame because my aim was to do the road circuits, not ovals, I wouldn’t do ovals but to do all the road courses, but it just didn’t happen.
“If COVID didn’t happen, it probably would [have happened]. But I’m sure a lot of people can say the same thing.”
