Hamilton was forced to retire as a result, while Russell managed to recover from a spin, a wing replacement and an additional pit stop to ultimately secure fourth place and salvage what he could from the race weekend.
Rosberg acknowledged that it was only a 'slight misjudgment' on Hamilton's part, but it had significant consequences.
“Yeah, George thought the race was over, but actually [it] turns out [it wasn’t]," the 2016 world champion told Sky Sports F1. "This is going to be interesting to analyse obviously, Lewis has the soft tyres so he just tries to go round the outside but it’s three people going into turn one.
"It was 100% Lewis’ error there, it’s a slight misjudgment, it’s not a big misjudgment, [he] doesn’t leave quite enough space for Geroge there, so it’s all on Lewis. He already admitted to [it] and kind of took responsibility for it."
Hamilton issues apology
Hamilton initially believed that Russell had caused the first-corner accident, but he U-turned after seeing the incident back.
"No hard feelings," he wrote. "We’re here to fight and maximise for the team. We misjudged it today, but our car was exceptionally strong and I’m proud of the whole team. Time to regroup and continue building off the strong pace in Austin."
