One thing is certain. Koivu will not play tonight and the best-case scenario is that he is likely done for the remainder of the playoffs. Koivu will remain in hospital until the tests are done and while the Canadiens are not saying publicly, one source close to the team said Koivu still cannot see out of the eye.
How does he know what the best case scenario is? The sentence doesn't even make sense. The best case scenario can't be that he's "likely" to miss the rest of the playoffs. The best case scenario is likely that his career won't be jeopardized. That would make sense. But he couldn't know that unless he had information he didn't include in the story.
