Why did Osby only have 18 minutes?

[Oscar Uniform]

The box score shows he only had 18 minutes. It also shows he had zero fouls. Was he injured? If he and Can were the 2 best players on the court, there is no reason he should have only 18 minutes. It doesn't matter that they play roughly the same position. Each one of them is a better 4 or 5 than anybody else on the team.

Those are not correct. I don't know how many minutes he played, but I know he had 4 personal fouls
