Becky James won her first senior world title with a thrilling victory in the women's individual sprint at the Track Cycling World Championships in Minsk.
Although Kenny will not be on the podium,
Laura Trott is on course to win a medal in the women's omnium.
The defending champion started the six-race event well with a third place in the flying lap, before a less impressive 10th in the points race saw her drop to fifth overall.
But she bounced back brilliantly in the third event of six, winning the elimination race to move into the bronze medal position with three events remaining on Sunday. The United States' Sarah Hammer is the overnight leader.
Dibben digs in
Jon Dibben ended the men's omnium in an impressive eighth place on his world championship debut. Having won the fifth of six races, the scratch race, earlier in the day, the 19-year-old then posted the 12th best time in the concluding 1km time trial.
The gold was won by New Zealand's Adam Gate, with Olympic champion Lasse Hansen (Den) taking silver and Glenn O'Shea (Aus) bronze.
Dibben said: "I am happy with the way it has gone. Eighth is a solid result for me. The omnium is hard - six races in two days. You never have too much time lying around. You have to stay on your toes and try and take it in your stride."
In the women's points race,
Dani King was unable to repeat the heroics of compatriot Simon Yates 24 hours earlier in the men's version, finishing eighth, having never really threatened the top of the standings. Jamila Machacova (Cze) took gold, ahead of Sofia Arreola (Mex) in second and Georgia Bronzini (Ita) in third.
