Track Cycling Worlds 2014: Crash costs Jason Kenny in keirin final

Great Britain's Jason Kenny says he "got a bit tangled" on the last lap of the keirin final at the Track Cycling World Championships in Colombia as avoiding a crash cost him a medal.

Kenny, who won sprint gold at London 2012, was run out of contention when Germany's Max Levy crashed and forced him on to the upper part of the track.

Matthew Glaetzer earlier suffered a spectacular crash during a heat when his bike bounced off the track and into the commentary box.
