Three-time Olympic champion Jason Kenny will return from the Track Cycling World Championships without stepping foot on the podium after his early elimination from the sprint as Great Britain were blanked on the penultimate day of competition.

The 25-year-old from Bolton had to settle for a hat-trick of fifth-place finishes after his quarter-final elimination in the sprint to France's Francois Pervis, who has won two gold medals already and is on course for another on Sunday's final day.

With Ed Clancy finishing fifth in the men's omnium, Britain's men have one final, and unlikely, opportunity to claim a medal at the championships, in the unpredictable Madison through Jon Dibben and Owain Doull.

The laid-back Kenny was unable to reveal reasons for the poor performances of Britain's men. Clancy struggled to do so, too.

Kenny's day was challenging from the moment he qualified in a lowly 14th place, giving him a difficult route to the knockout stages.

He lost to Germany's Stefan Botticher in the second round, falling into the repechage before advancing at the second attempt - team-mate Matt Crampton was eliminated - to face Pervis, who won their last-eight duel 2-0.

"It's fractions," Kenny said. "Unfortunately we're at the wrong end of those fractions. We want to be fractions in front instead of fractions behind.

"The three fifths tend to speak for themselves. I feel a little bit behind the top runners."
