INDIANAPOLIS — Marcus Ericsson returned to the Indianapolis 500 with zero regrets but ended Thursday with a violent collision late in the first full day of practice.
Ericsson hit a curb with just over two hours remaining in the session, causing his car to spin and hit the wall three different times.
''Obviously it was quite a decent hit, but the safety in these cars is pretty impressive, so feeling OK,'' Ericsson said. "I'm very disappointed and very sorry for my team. They've done a very good job and they have a lot of work ahead of them now and that's probably the worst.
''I think we were in good shape, but obviously you have a big crash like this, it sets everything back to zero. It is what it is — we just have to bounce back.''
But before the crash, Ericsson had moved past the controversial ending to last year's race that cost the Swede a second consecutive win in the ''Greatest Spectacle in Racing.'' And, he has made up with teammate Colton Herta following their spat last weekend.
As for his move from powerhouse Chip Ganassi Racing to Andretti Global, where Ericsson's results have shown a sharp drop-off?
Nope. Nothing to be concerned about there, either.
''Why would I have regrets?'' Ericsson asked Thursday. ''You should never have regrets.''
