London: World champion Jason Kenny was surprisingly knocked out of the men`s sprint event at the London track World Cup when he lost to German Maximilian Levy in the quarter-finals on Sunday.
The Briton seemed to lack energy as he was comfortably beaten 2-0 by German Maximilian Levy.
His defeat could seriously affect his chances of an Olympic spot in the discipline, especially if fellow-Briton Chris Hoy, the Olympic champion, goes through later on Sunday.
Hoy was locked at 1-1 with France`s Gregory Bauge as the tie was sent to a decider.
Only one rider from each nation is allowed to take part in the men`s individual sprint.
Frenchman Kevin Sireau easily beat Team Sky`s Matt Crampton of Britain to reach the semi-finals.
