Romain Grosjean confronts Marcus Armstrong after Sonsio Grand Prix: 'I want to punch you'
INDIANAPOLIS – Tensions flared between Romain Grosjean and Marcus Armstrong following Saturday's Sonsio Grand Prix at the Indianapolis Motor Speedway.
After getting out of his car, Grosjean — who finished 21st in the race — approached the pit box of Armstrong — who finished 11th. Video captured outside of Armstrong's pit box shows Grosjean making his way to confront Armstrong after initially being held back by members of Armstrong's No. 66 pit crew.
"Get off," Grosjean said to the crew members in a video captured by Racer Magazine. "I was going to talk to him. I was going to say I want to punch you."
Grosjean eventually got face-to-face with Armstrong while crew members stepped between them.
"I have never punched anyone in my life," he proceeded to say.
There’s a reason to hire a crew chief like Jimmy Looper who also serves as head of security for his car and peacekeeper for his driver. Good to see Romain throttle back. #racing#motorsport#indycarpic.twitter.com/9PBBZBaMJr

It is unclear what caused the dispute between the two drivers, who finished 10 spots apart in the race and whose pit boxes were 10 spots away from one another.
"He fancied a bit of a fist fight, actually," Armstrong told Fox. "A bit of UFC, a bit of MMA — something I'm not accustomed to. But hey, you know what, I've got like a 350-pound fueler who was like right behind me, so fair play to Romain, he's got some balls for trying to attack me with him behind me."
