The 30-year-old, who suffered a cardiac arrest during Denmark's Euro 2020 clash with Finland last June, has impressed since joining Brentford on a free transfer in January.

He registered an assist during the Bees' 2-0 win over Burnley this month with what was his first goal involvement since his return to football.

Eriksen's strong club form led him to receive a call-up for his country's upcoming friendly matches, but the positive test will delay the midfielder's journey to meet up with the squad.

Although, Denmark boss Kasper Hjulmand hopes the Brentford man will still be available to feature in clashes against the Netherlands – to be played at the home of Eriksen's former club Ajax – and against Serbia in Copenhagen. 

"We've been running dialogue with Christian and Brentford on the situation," Hjulmand said.

"We expect to see Christian as soon as possible, later in the week. 

"We are happy to get him in the team and expect to have him with us for the exciting friendly matches against Holland and Serbia."

The creative midfielder's positive test ruled him out of Brentford' Premier League clash with Leicester City on Sunday, despite Bees boss Thomas Frank claiming during his pre-match media duties that Eriksen had since returned a negative test result.

Eriksen has earned 109 caps for Denmark – putting him 20 appearances short of Peter Schmeichel's record of 129 outings for his country – and has scored 36 international goals.
