"As far as I know, Bret will be there unless his doctors tell him otherwise," Michaels' representative toldPeople in a Friday report. "We're cautiously optimistic that he will attend the finale. But ultimately, it's up to his doctors."
Michaels and actress Holly Robinson Peete are the two remaining finalists vying for The Celebrity Apprentice's third-season title, which will be awarded during Sunday night's live finale broadcast on NBC.
Michaels was readmitted to the hospital after suffering numbness on the left side of his body, predominately his face and hands -- which doctors subsequently described as a "warning stroke" that revealed a small hole in his heart.
However Michaels' neurosurgeon Dr. Joseph Zabramski stated it is "highly unlikely" the warning stroke is connected to the hemorrhage.
Dr. Keith A. Siller -- NYU Comprehensive Stroke Care Center's medical director -- told People he feels that Michaels could fly from his Arizona home to The Celebrity Apprentice's finale in New York City because he is on blood thinners to prevent further clots.
"Being on a blood thinner -- which is one treatment that can be offered in the interim while they decide what to do [about the hole in his heart] -- does give him some protection, so he probably could fly," Siller, who has not treated Michaels, told People.
"As long as he's on the blood thinners, that offers him significant protection against another stroke even with the hole not being closed."
While Siller said Michaels could theoretically fly, Zabramski stated he's not sure if it's advisable.
"Without a doubt he is very determined to get healthy and make a 100 percent recovery. Medically speaking it is a fantastic attitude both mentally and physically for him to have," said Zabramski on Michaels' personal website.
"However, Bret's brain and body are not quite 100 percent yet, especially with the hole found in his heart."
