Zlatan Ibrahimović has tested positive for COVID-19, the AC Milan forward announced on Twitter.

“I tested negative to Covid yesterday and positive today,” Ibrahimović wrote. “No symptoms what so ever. Covid had the courage to challenge me. Bad idea.”

He was placed in quarantine at his home, per an official statement from the team.

Ibrahimović, 38, tested positive in the second round of swab tests conducted after a teammate tested positive on Wednesday. Yahoo Sports is not using names of those reported to have COVID-19 unless the person confirms the news publicly.

All other players and staff came back with negative tests, the team said. AC Milan is scheduled to play Bodo/Glimt on Thursday in the third qualifying round of the Europa League.

Ibrahimović signed a new one-year contract with the club worth a reported $8.3 million. He left the Los Angeles Galaxy after scoring 52 goals in 53 starts.
