AC Milan striker, Zlatan Ibrahimovic has tested positive for coronavirus, a day after testing negative.
According to a tweet by Ibrahimovic, he had tested negative a day before another test result came back positive.
The tweet also indicated that he was asymptomatic.
Ibrahimovic tweeted: "I tested negative to Covid yesterday and positive today. No symptoms whatsoever.
"Covid had the courage to challenge me. Bad idea."
The announcement came just hours before Milan are due to take on Norwegian side FK Bodo/Glimt in the Europa League third qualifying round on Thursday.
According AC Milan, "relevant authorities" have been informed of Ibrahimovic's health status.
The club also noted that he will enter a period of quarantine at home.
Milan added that no other members of the squad have tested positive in the latest round of testing, although defender Leo Duarte did return a positive result on Wednesday and has already begun isolating.
Ibrahimovic scored both goals in Milan's 2-0 win over Bologna on Monday.
The 38-year-old former Sweden international signed a new one-year deal at the San Siro this summer following his successful return to the club from the LA Galaxy in January.
