Chris Bosh (Heat) still undergoing more tests at hospital

Chris Bosh of the Miami Heat was undergoing more tests on Friday, amid concerns that he has a blood clot on one of his lungs.

Heat coach Erik Spoelstra told reporters in New York that "it's too early for an ultimate diagnosis." Spoelstra says the team will have more information either later Friday or sometime Saturday.

Bosh has been dealing with side and back pain for several days. He went to a Miami-area hospital on Thursday for evaluation, and Spoelstra says the All-Star forward "is in great care and good spirits."

Miami is playing at New York on Friday night, though that almost seemed secondary amid worries about Bosh's condition.
