Injured Aussie Matthews out of Tour de France
Australian Michael Matthews poses before the start of the 8th stage of the 97th Giro d'Italia, Tour of Italy, cycling race from Foligno to Montecopiolo on May 17, 2014 in Foligno - by Luk Benies
He has been replaced in the Australian Orica GreenEDGE team by Canadian Christian Meier.
Matthews, a 23-year-old sprinter from Canberra, fell during a training ride at the beginning of the week, suffering cuts and abrasions down his left arm and leg.
He also required six stitches in his palm.
Meier, 29, had to fly in from Vancouver on Thursday night.
"It hasn't really sunk in yet, it has been a little bit of a whirlwind 24 hours," Meier said.
"It's not the way you want to start a Tour just because a guy is injured, but I have to say, as my first Tour I am extremely excited to start.
"It's every bike rider's dream to do the Tour de France one day and it's unbelievable that it is happening."
The news further disrupts Orica's Tour preparations, coming just a couple of days after they announced that South African Daryl Impey had failed a doping test.
Last year Impey was the first ever African to wear the Tour's fabled yellow jersey.
