Kevin Magnussen's trainer and physio has said that the Dane will definitely be at Monza this weekend.
The 40-plus G impact at the Eau Rouge corner at the Belgian Grand Prix on Sunday broke his protective cockpit collar and meant a hospital check for the Renault driver.
"He will have a lot of treatment now and not just in one place," Thomas Jorgensen, Magnussen's physio, told newspaper BT. "It's his entire body."
Magnussen cut his ankle in the smash but Jorgensen said that all of the 23-year-old's muscles, tendons and joints will be sore.
"He had a whole-body scan yesterday because the G effect was so high. But there was no bleeding of the organs so we have the green light on that, also with his neck," he said.
"It's up to how Kevin responds, but he'll be there - I know him well enough to know that. He will take it easy in this week now and move on."
To be declared fit for Monza, Magnussen will have to be checked and cleared by FIA doctors on Thursday.
