The action at today's Indy 500 has been dangerous at times. We've seen several people affected.
First, a crew member was injured during an earlier pit stop. It happened when he was struck by a tire.
Then, there was a rather gnarly crash. Several cars were involved, though it looks like it could have been even worse.
You can see the footage of the wreck below. Fortunately, it doesn't look like anyone was seriously hurt.
As skilled as all of these drivers are, accidents like this are inevitable. You put that many cars on a track going that fast over a 500-mile stretch, there will be some mishaps.
You can view the rest of the Indy 500 from Indianapolis Motor Speedway on NBC.
Will Power (yes, that is his real name) won last year's event and is racing today to defend his crown.
