Safety comes first, says Jenson Button

On the advice of doctors, Alonso is absent from the season-opening Australian Grand Prix after sustaining concussion following a heavy crash on the final day of the second pre-season test last month.
Fears were expressed to Alonso of ‘second-impact syndrome’ whereby a serious brain injury, or even death, could occur should the 33-year-old be involved in a second incident so soon after the first.
