Actually, that was the question back when the article appeared. And, since no additional surgery was scheduled at that time, the expectation seemed to be that the antibiotic treatment was sufficient to deal with it. Now, a month later, with no reports of surgeries actually being performed, it continues to appear that the antibiotic treatment was/is working.
The article, at the time, made it sound like additional surgeries were imminent. That appeared to be speculative reporting, at best.
My assumption is that the fairly decent health care system in Boston is probably capable of treating an orthopaedic injury, even with infection complications with a prognosis that is better than career-ending. Could it go bad? Sure, but that would not be the baseline assumption.

BTW, I believe the original source for the doomsday article was Ron Borges, not Mike Reiss.
