Four-time Olympic champion Laura Kenny is a doubt for April's Track Cycling World Championships in Hong Kong after suffering a hamstring injury.
The 24-year-old, who won two gold medals at both the London 2012 and Rio 2016 Olympics, has withdrawn from this month's Six Day event in Berlin and the British Championships at the Manchester Velodrome.
No timescale given for her recovery, meaning Kenny's return to global competition may also be delayed.
British Cycling said in a statement: "British Cycling's Laura Kenny has withdrawn from the forthcoming Six Day Berlin and HSBC UK National Track Championships having sustained a hamstring strain.
"Laura is undergoing treatment and hopes to return to full fitness soon."
Riders often opt to miss the first World Championships following an Olympics to take a break early in the four-year cycle between Games.
Six Day Berlin begins on Thursday, while the British Championships take place from January 27.
The Hong Kong Track World Championships take place from April 12 to 16.
