If Treinen is unavailable on Saturday and is not being evaluated until Monday, it sounds like he will not be available on Sunday, either. For pitchers, elbow discomfort is always a concerning development because it can be a warning sign of a more serious issue. More information should be available Monday or Tuesday after he is evaluated.
