British track endurance rider Lizzie Armitstead has been forced to pull out of this month's UCI Track Cycling World Championships in the Netherlands (March 23-27) due to injury.
Armitstead was scheduled to ride the omnium, but is suffering from side strain.
British Cycling has said that Armitstead is receiving treatment for the strain and is expected to make a full recovery but not in time for the track worlds.
Laura Trott - whose name was already on the worlds roster - will take Armitstead's place in the multi-discipline omnium.
Britain's pick for the women's team pursuit will be announced next week.
