Bickerstaff’s proclamation about progress were positive signs, sources tell cleveland.com there’s pessimism surrounding Allen’s availability Tuesday night.

Another source called him playing “unrealistic,” only leaving open the possibility based on Allen’s extreme competitiveness level. The Cavs are expected to practice before leaving for New York Monday afternoon.
