MIAMI -- Chris Boshs plan to resume playing is now in jeopardy, after medical examinations performed in recent days convinced the Miami Heat that he is not healthy enough to return to the court.And Bosh may have provided a clue why.The Heat announced Friday that they still cannot clear Bosh for a resumption of basketball activities, based on the result of his preseason physical -- a series of tests conducted over the past few days. Their announcement came two days after Bosh revealed in the first chapter of a documentary series about his saga that he had multiple clots in February.The Miami Heat regret that it remains unable to clear Chris to return to basketball activities, and there is no timetable for his return, the team said Friday.Late Friday, Bosh released a statement, saying little setbacks happen.But that doesnt change my intentions and what I want to accomplish, Bosh said.That statement was distributed by LeBron James digital platform called Uninterrupted, the same site that Bosh worked with for the documentary. In a video posted there earlier this week, Bosh said a small clot was found in his leg this past February when he was in Toronto for the All-Star break, and that a CT scan later found the existence of at least one other clot.Typically, CT scans are administered when clots are expected of having traveled to a lung -- a very serious condition called a pulmonary embolism, which Bosh also had in February 2015 in his first bout against the problem that now threatens his career.I wouldnt be a friend if I didnt express to him my concerns, former Heat guard Dwyane Wade, now a member of the Chicago Bulls, told The Associated Press. To me, the biggest thing is Chris has five kids and a wife and a family that depends on him being there. To me, thats always most important. I told him, `Make sure you focus on that first.The next step for Bosh is unclear. The Heat will hold media day on Monday and their first practice of the post-Wade era in the Bahamas when training camp opens on Tuesday.Bosh wont be on the floor for that practice, and likely not anytime soon -- if ever. That means the Heat are for now down to just one player left from the team that played in the NBA Finals just two years ago, that being veteran forward Udonis Haslem.Hate to hear that about Chris Bosh, Oklahoma Citys Enes Kanter tweeted Friday. Im sorry brother. Praying for you my man.Everything about Boshs future remains murky, and the Heat are unable to shed any light on their perspective, either. The team said it cannot comment further on Boshs status because of a rule in the NBAs Collective Bargaining Agreement which precludes a team from releasing certain medical information without a players consent.What figures to come in the next days, weeks and possibly months is more tension between the Heat and their highest-paid player, wholl make $76 million in the next three years whether he plays or not.Im ready to play, Bosh said last week .The Heat -- as well as doctors in Miami and New York, where Bosh was earlier this week -- do not agree.There are mechanisms in the CBA that would allow Miami to get Boshs salary off its cap number sometime next year if he cannot continue to play. But the Heat reiterated Friday that their goal for months has been to get Bosh back on the floor as quickly as possible.Boshs first bout with a clot was in February 2015, when one that was believed to have formed in one of his legs traveled to a lung and caused problems so severe that he needed to be hospitalized for several days.He recovered and was averaging 19.1 points last season when the second bout with clots began this past February.Bosh, in the podcast with Uninterrupted last week and the video on the site earlier this week, made minimal attempt to hide his frustration with Heat doctors -- saying they work for the team and not the player, then adding that they told him in February that his career is likely over.I think that I have the right to disagree, Bosh said.For now, any sort of agreement seems a long way off.

NORMAN, Okla. -- There might be a silver lining in Oklahomas season-opening loss.Houston quarterback Greg Ward shredded the Sooners in a 33-23 victory that knocked Oklahoma from No. 3 to No. 14 in the AP poll , but the Cougars might have done the Sooners a favor by showing them what they need to fix in the secondary with Ohio State looming on Sept. 17. Oklahoma will start the process Saturday against Louisiana-Monroe.When you lose, its hard to look at some of those positives for us, Oklahoma defensive coordinator Mike Stoops said. In the long run, Im sure it will pay off, we hope. We recognize that when you play a team like that (Houston), it exposes some of your weaknesses immediately.Stoops said there could be changes in the secondary. Ward passed for 321 yards and two touchdowns, and the Sooners got beat deep at times and struggled to tackle. Dakota Austin and Parrish Cobb, in particular, got picked on. Stoops said P.J. Mbanasor and former receiver Michiah Quick could get serious looks this week.Its pretty open right now, Stoops said. Well see who is the most consistent player out there. We need somebody to be consistent. You arent going to win every 50-50 ball, but you have to win your share. When they (the other team) win every time, that becomes a problem.Oklahoma will face another versatile quarterback on Saturday. Louisiana-Monroes Garrett Smith passed for 208 yards and two touchdowns and ran for 150 yards and another score in a season-opening win over Southern. With Houstons success through the air, Stoops said, Oklahomas defensive backs can expect to be tested Saturday.The ball is going to keep coming, Stoops said. Thats one thing they ought to be ready for because its going to keep coming, so you just have too take it on as a personal challenge.dddddddddddd. To me, thats your pride and technique and thats why you are here. Were going to be challenged, and you have to be up for it. Well find out who is man enough for the challenge and who isnt.Houston avoided Oklahoma star cornerback Jordan Thomas and targeted the others. That makes the need for a cornerback other than Thomas to become a consistent playmaker critical.Its huge, Thomas said. That way, they (the other corners) dont feel like theyre in the hot seat. They dont have that much more stress on them to play perfect or to make a certain play here or here. I feel like its really, really crucial to our defense.All was not bad against the Cougars. Houston, a prolific running team a year ago, managed just 89 yards on 40 carries. Ward, who rushed for 1,114 yards last season, managed just one yard on 18 carries against the sooners.If you would have told me wed have held that team to 80 yards rushing and lost, I would have thought you were crazy, Stoops said. But its still finding the balance between putting all that pressure on guys that maybe cant handle it, finding ways to help.Stoops hopes the players learned a valuable lesson about preparation after falling short in that area before the Houston game.If you get too full of yourself -- and you can be overly confident and not prepare the right way -- then youre going to get humbled, he said. In this game, youre always one game, one play away from always getting humbled. Thats why you have to always stay the course and always prepare and work at it.---Follow Cliff Brunt on Twitter (at)CliffBruntAP ' ' '
