Nicolas Jackson last played for Chelsea at the Club World Cup in June
Chelsea have told Bayern Munich they have revoked permission for Nicolas Jackson to conduct a medical with them and have instructed the striker to return to London - having travelled to Germany to complete a loan move.
Sources have told BBC Sport that the 24-year-old is angry with the collapse of his initial £13m loan deal, and attempts are expected to be made to salvage it.
The decision was made after striker Liam Delap suffered a serious-looking hamstring injury in Chelsea's 2-0 win over Fulham on Saturday, with manager Enzo Maresca saying post match that he may be out for "six to eight weeks".
It follows a remarkable whirlwind 24 hours in which Chelsea went from having four strikers to just one.
