The team said the All-Star is receiving care guided by Heat physicans at a South Florida hospital and resting comfortably. The problem, if it had not been caught, could have killed the 30-year-old Bosh, who had been fighting pain in his side and back for several days.
“Chris is OK and his prognosis is good,” the Heat said in a statement.
Heat coach Erik Spoelstra was scheduled to address reporters later Saturday, before Miami hosted the New Orleans Pelicans.
The medication required to treat such a condition typically requires at least six months of limited physical activity.
In cases like these, it’s common for the clots to have worked their way from the legs to the lungs, a dangerous occurrence. Blood clots are always a serious condition, but this is a particularly scary moment for Bosh and the NBA after former Portland Trail Blazers star Jerome Kersey died suddenly Wednesday of a blood clot in his lung. Kersey was 52.
Last month, Brooklyn forward Mirza Teletovic was ruled out for the season once clots were found on his lungs. Cleveland’s Anderson Varejao went through a similar situation and missed most of the 2012-13 season.
Bosh was admitted to the hospital on Thursday after complaining about discomfort in his chest for several days.
Bosh spent the early part of this week on vacation with family and friends, including teammate Dwyane Wade, in Haiti. Wade said Bosh wasn’t “feeling his best” on the vacation. When Bosh hadn’t improved by Wednesday, he was sent to a team doctor, and from there went to the hospital for tests.
“There just came a point in the vacation where he didn’t feel right,” Wade said. “He kind of relaxed and rested, and then when he got back, he did what he should have done … [he] got to the doctor and tried to see what’s up.”
Losing Bosh is nothing short of a shock to the Heat, who entered Saturday with a 23-30 record and holding onto the No. 7 spot in the Eastern Conference playoff race.
He was averaging 21.1 points and 7.0 rebounds this season, his first in a five-year deal signed this past summer that will pay him $118 million.
Bosh is the second NBA player whose final game this season was the All-Star Game. New York’s Carmelo Anthony was shut down for knee surgery earlier in the week, a move that was long expected.
