Chris Bosh hasn't taken to an NBA floor for two-and-a-half years after suffering from blood-clotting issues but he still hasn't given up hope of making a comeback.His health problems led to his exit from the Miami Heat after the team's doctors declared that he wasn't able to play as he failed a medical.The blood-clotting cut his season short in both 2014-15 and 2015-16 and became a major issue with the Heat.After a medical review, they were able to clear the remaining $52.1 million on his contract from their salary cap last summer and effectively end his career in Miami.But Bosh still has a burning desire to play and refuses to close the door on a potential return.“Yeah, it’s still on my mind,” Bosh told Yahoo Sports of his comeback attempt.“Obviously, if it doesn’t happen by February, I’m not stupid, but yeah, I’m still looking forward to that."I’m still trying to overcome that hump and trying to get something going. I’m looking forward to the challenge."I know I can still play some ball and be a 3-and-D guy for somebody out there.”

Race against time

At 34, he understands that time is running out for him and he'll have to accept that it won't happen if a team doesn't take a gamble on him in the next five months.

The 11-time All-Star has seemingly given himself until February - the trade deadline - to make a return.

February 9 will mark three years to the day of his last game and he'll have to seriously consider announcing his retirement if he isn't cleared to play by that date.

But Miami's reluctance to play the veteran again means it's unlikely that the rest of the league will take a gamble on his health.

“If he was healthy, he’d be playing for the Miami Heat right now,” a general manager told ESPN in March.

“The fact they determined it was not an option makes me say we’re not going there.”

The Heat signed Bosh to a huge contract in 2014 and beat off stiff competition from the Houston Rockets to re-sign him as a free agent.

Their decision to stop playing him wouldn't have come easy as he was one of their star players but they were not going to ignore the medical advice they received.

The chances of him being cleared by doctors of another team appear to be slim but he's not prepared to say goodbye to the game just yet.
