MIAMI (AFP) - Miami Heat forward Chris Bosh was ruled out of his team's next match on Wednesday amid reports he was battling a fresh blood clot.

Bosh withdrew from the All-Star Game before reports appeared saying he had suffered a recurrence of the blood clot problem which wrecked his season last year.

A statement from the Heat did not explain why Bosh would miss Friday's game against the Atlanta Hawks.

"When further information is available that we can pass along, it will be provided," the Heat said in the statement.

Bosh missed the final 30 games of the season last year because of blood clots that moved to his lungs from an earlier calf injury.

Bosh, 31, has averaged 19.1 points and 7.4 rebounds per game this season.

He won NBA championships with the Heat in 2012 and 2013 and has been named an NBA All-Star 11 times.
