The Belgium international striker will be undergoing medical tests before heading back to Stamford Bridge for a return to domestic duty
Romelu Lukaku has handed Chelsea an untimely injury scare by admitting that he will be undergoing a scan on a "minor issue" before returning to Stamford Bridge from international duty.
The 28-year-old striker, who returned to west London in a £98 million ($136m) deal during the summer transfer window, has been away with Belgium in World Cup qualifying action.
He collected his 100th cap for his country against the Czech Republic on Sunday, with a caution in that contest meaning that he will be suspended for the clash with Belarus on Wednesday.
