Benni McCarthy has been ruled out of Blackburn's Uefa Cup match against MyPa on Thursday.
The South African striker suffered concussion at the weekend following a clash of heads with Chris Riggott during Rovers' 2-1 victory over Middlesbrough.
He later admitted the incident had been one of the 'worst moments' of his career, but was allowed to return to Blackburn with the rest of his team-mates after undergoing scans in hospital.
However, it has been decided that he will remain at home when Blackburn travel to Finland on Wednesday.
Mark Hughes explained: "Benni has been checked over again and is okay.
"But he got a bang on the temple, which shook him up, and the MyPa game has come too soon for him."
