Michael Conlan's proposed world title eliminator against Isaac Dogboe on 5 December is off after the Belfast featherweight revealed he ruptured ankle ligaments in his right leg earlier this week. 

Conlan was said to be closing in on a bout against the Ghanaian-British fighter - the former WBO super-bantamweight champion - as he looked to advance his claims towards fighting for a world title next year. 

But he wrote on Twitter: "Absolutely devastated to announce I will no longer be fighting December 5th due to rupturing my ATFL during a training session on Wednesday, back home now recovering. 

"Doc said I'll be out for 8-12 weeks but I'll be back sooner, just watch!" 

The former amateur world champion, 28, is undefeated in 14 professional fights and was last in action against Sofiane Takoucht in August. 

Conlan, who won Olympic bronze at London 2012, was due to drop down four pounds from featherweight in a bid to set up a world title in 2021.
