Fernando Alonso is back in training after missing last weekend's Bahrain Grand Prix due to rib fractures, which he sustained in the season-opening Australian Grand Prix.
Alonso suffered the injury in a high-speed crash at Albert Park and was not passed fit by FIA doctors during a mandatory medical assessment in Bahrain.
He was consequently replaced by reserve driver Stoffel Vandoorne, who went on to collect McLaren's first point of the season after placing 10th.
Alonso told Sky Sports F1 on the grid in Bahrain that he was "99%" sure of returning to action in China next weekend and the Spaniard has now resumed partial training.
"Return to the training," he posted on social media. "In the next few days I hope to do also cycling and swimming. Step by step."
Alonso will have to pass another medical check-up by FIA officials next Thursday at Shanghai.
