LONDON, (Reuters) – Amir Khan’s first crack at a  world title could be postponed because Ukrainian WBA world  light-welterweight champion Andreas Kotelnik has a tooth  infection, Khan’s promoters said. The fight is planned for June 27 in London but the  31-year-old Kotelnik damaged a tooth while sparring and it has  become infected.  

“We are just waiting to hear back from his promoters,” a  spokesman for Frank Warren, Khan’s promoter said yesterday.  “It’s all a bit up in the air at the moment.  

Briton Khan, the Olympic silver medallist at lightweight in  2004, has stepped up to light-welterweight for his first world  title fight.

His promoters said another opponent would be sought  should Kotelnik be unable to fight.
