Lewis Hamilton behind the wheel again as Mercedes star eases fears he will miss Canadian Grand Prix with back injury

LEWIS HAMILTON has returned to a single-seater motorcar to ease fears he could miss the Canadian Grand Prix with a back injury.

The seven-time F1 world champion, 37, was seen clutching his back in agony following the Azerbaijan GP as a result of his Mercedes' crippling porpoising issue.

Hamilton managed to finish a creditable fourth on the gruelling street circuit in Baku.

But both he and team-mate George Russell - who came third - moaned about their "bouncing" car throughout the weekend.

There were fears Hamilton would have to skip the Montreal race with his back battered and bruised across the three days.

The Brit legend even described his back as a "mess".

However, Hamilton has allayed those fears by sharing a snap of himself back behind the wheel of a low-sitting car ahead of this weekend's Canadian GP.

The Mercedes man shared the simple snap with a somewhat tongue-in-cheek caption, which read: "Back to it."

Earlier this week, Hamilton revealed he "wouldn't miss the Canadian GP for the world".

On Monday, he said: "Good morning world. Yesterday was tough and had some troubles sleeping but have woke up feeling positive today!

"Back is a little sore and bruised but nothing serious thankfully.

"I've had acupuncture and physio with Ang and am on the way to my team to work with them on improving.

"We have to keep fighting.

"No time like the present to pull together and we will. I'll be there this weekend, wouldn't miss it for the world.

"Wishing everybody an amazing day and week."

Hamilton revealed he has been having physio and acupuncture from Angela Cullen, who has been working with the F1 star since 2016.

Cullen has been tasked with helping Hamilton to get fit and ready to go in time for this weekend's race.

The former McLaren star heads into the race 88 points behind championship leader Max Verstappen.

But for Hamilton and Mercedes, the team will first hope to resolve their porpoising issue as they target a strong remainder of the season following their shaky start.

Russell has revealed Hamilton will turn into a "beast" once the mechanics get to the bottom of the issue.

And with plenty of races to go, the Brit pair will be hopeful of finally launching a genuine challenge to the Red Bulls and Ferraris.
