The Ardennes Classics, the Flèche Wallone in particular, seem tailormade for Colombian climber, but his participation is jeopardised by a knee injury.

At the time of writing it remains highly dubious whether Carlos Betancur will make it to the starting line in the Ardennes Classics. The Colombian AG2R La Mondiale rider is struggling with an infection that has his team doctors baffled.

"It looks very bad for the Amstel Gold Race, Flèche Wallonne and Liège-Bastogne-Liège," said team manager Vincent Lavenu according to Wielerflits.nl. The winner of the Paris-Nice was compelled to leave the Tour of the Basque Country last week, dropping out because of knee problems that continue to plaque him.
