Romain Grosjean was involved in an altercation with IndyCar rival Marcus Armstrong after this weekend's race.

Grosjean - who previously raced in F1 for Haas - now races for Dale Coyne Racing in IndyCar, and at the Sonsio Grand Prix this weekend, the Frenchman finished down in 21st - last of the remaining runners.

But 40-year-old Grosjean still appears to have plenty of fight left in him. Following an incident with the No.66 of Marcus Armstrong, Grosjean was left with suspension damage very early on in the race.

Armstrong went off the track before rejoining and crashing into another car who had gone way off track, with Grosjean then caught in the middle and unable to get out of the way.

Following the race, Grosjean was not happy with Armstrong's role in the incident, storming up to his Meyer Shank Racing garage and having to be held back by team members. Grosjean can be heard in the video saying 'I was going to say I want to punch you’.

"But hey, you know what? I've got a 350-pound fueler who was, like, right behind me, so fair played to Romain, he's got some balls for trying to attack me with him behind me."

Grosjean was just 'joking'

Grosjean calmed down by the end of the altercation and was telling Armstrong that he had a lot of respect for him, also telling the '350-pound fueler' that he had never punched anybody in his life, as the team member still tried to protect Armstrong.

Afterwards, Grosjean told IndyCar reporter Marshall Pruett that it was all a big misunderstanding.

Pruett took to X to say: "Romain called to say he was simply trying to talk to Marcus and made a joke about wanting to punch him and that it was taken out of context and that’s where the misunderstanding happened."

40-year-old Grosjean now races in both IndyCar and the IMSA Sportscar Championship having left F1 in 2020 following a horror incident at the 2020 Bahrain Grand Prix which left him with severe burns on his hands.
