Fernando Alonso says he will race through the pain barrier this weekend in order to compete in the United States Grand Prix at the Circuit of the Americas.

The Spaniard was forced to undergo medical checks on his back following a heavy landing in Abu Dhabi after he ran across a kerb avoiding the Toro Rosso of Jean-Eric Vergne following his final stop.

Although given the all-clear, Alonso has continued to suffer discomfort in the time since the Yas Marina race but insisted it wouldn't prevent him from giving his all when he hits the track in Austin.

"Packing the bag for Austin, with some pain, but eager and confident to help the team," he wrote on Twitter. "I will try to give 100 per cent as always."

Ferrari president Luca di Montezemolo meanwhile was full of praise for Alonso for battling against the injury to ensure he can race this weekend.

"I am pleased to see that Fernando is so keen to give it his all, even when he's not at his best," he said. "It shows how attached he is to us and I am sure that his example will be a further boost for the whole team in its efforts to end this season in the best way possible."
