Twitter reacts: #staystrong Phil Hughes

Australia batsman Phil Hughes is in critical condition in a Sydney hospital after being struck on the head by a bouncer during a Sheffield Shield game on Tuesday, and the player is on life support after emergency surgery.

Hughes was playing for South Australia against New South Wales, and had made a half century, when he was hit by a Sean Abbott short ball. He bent over for a few second before collapsing face down, and he needed CPR on the field before being rushed away.

Twitter reacted instantly, and in a prolonged way, with players and pundits around the world waking up to the news. There was also support for Abbott, especially from current and former fast bowlers.
