Magnussen fractures left-hand in training accident

Kevin Magnussen won't be able to fulfil his reserve driver role at the Singapore or Japanese Grands Prix after fracturing his left-hand following a cycling accident.

The Danish driver is required to stand in for Fernando Alonso or Jenson Button should they be unable to race and therefore attends every race with McLaren as part of his reserve duties.

However during training, the 22-year-old fell of his bike and fractured his hand, ruling him out of any driving duties for roughly three weeks according to a McLaren spokesperson.

"Kevin has been training extensively on his bicycle over the past few weeks and months, but unfortunately he fell off it the other day," the spokesman said.

"He has sustained a small fracture in his left hand, but is expected to make a full recovery within the next three weeks or so."

The former McLaren driver is currently vying for a seat on the 2016 grid, with the new Haas F1 Team his best chance of returning to a full-time race seat.
