NEW YORK –Amid concern for Chris Bosh being treated for a blood clot in his lung, the focus Friday with the ailing Miami Heat center moved well beyond the court.

"It's not about basketball," teammate Dwyane Wade said following the Heat's morning shootaround at Baruch College, in advance of Friday night's game against the New York Knicks. "It's bigger than that."

Coach Erik Spoelstra stressed that the team had yet to receive a definitive diagnosis.

"For everybody to speculate, right now, at this stage, it's very premature," Spoelstra said. "My biggest thought last night and tonight, 'Is C.B. OK?' "

According to a source familiar with Bosh's treatment, there initially were conflicting diagnoses, which led to further testing Friday. The source, however, also said the situation was serious.

Spoelstra said the situation is not life-threatening.

"It's too early for any speculation," Spoelstra said. "He's in good care and spirits."

Bosh's wife, Adrienne, offered an afternoon update on Twitter.

"We are just staying focused on positivity and keeping him healthy," she wrote, adding a heart icon. "We appreciate all the Love and Support we have received from our Friends, Family and Fans. Just a quick update that [Chris] is doing OK."

Amid word of Bosh, 30, being treated for an ailment that likely will have him sidelined for the balance of the season, the NBA fraternity rallied around the All-Star.

As the Cleveland Cavaliers prepared for Friday night's game against the Washington Wizards, former Heat forward LeBron James spoke of his concern.

"Hopefully he'll be all right," James told media in Washington. "My prayers are up, my hands are open, my fingers are crossed for sure."

James and Bosh advanced to the NBA Finals each of the past four seasons as Heat teammates, winning championships in 2012 and '13.

"Basketball is a small thing when it comes to health and family," James said. "He's so connected to me, I feel it for sure. Every minute I'm checking to see if he's OK."
