Wall was injured during the second quarter of Game 1 of the Eastern Conference semifinals Sunday, a 104-98 Washington win. He had 18 points, 13 assists and seven rebounds in 38 minutes.
Wall practiced on Tuesday but did not play in Game 2 that night, which the Wizards lost 106-90. Wall had told reporters Tuesday morning that he would play in Game 2, and Wizards coach Randy Wittman said less than two hours before tipoff that all of his players were available.
TNT's David Aldridge reported Wednesday that Wall would seek a second opinion on his injury.
A non-displaced fracture is a crack in the bone where the bone remains in its normal alignment.
