In the first place, what the hell does "questionable" mean? Because I didn't know, I looked it up. The first definition is "of doubtful propriety, honesty, morality." The second definition is "open to question or dispute." The third is "open to question as to being of the nature or value suggested." Example phrases are: "questionable activity." "a statement of questionable accuracy." and "a questionable privilege."
So while some folks would like to believe her condition is open to question, whatever that means, none of this exactly applies to a medical condition, unless they are saying that their description of the condition is questionable. In other words, maybe we should not believe it.
It has been my (admittedly limited) experience that team descriptions of an injury, especially after only a day or part of a day, really should be questioned. I think the person who said it's a placeholder is onto something. Coaching staffs game these things all the time. Pay no attention to the announcement until the team says the description is what the doctor said, and the prognosis is the doctor's.
