Wall scored 31 points in a game against the New Orleans Hornets, but spent the Wizards' third game in as many days dressed in a T-shirt and sweatpants. The former Kentucky star was leading the Summer League in assists and was second in scoring coming into the day.
Leo Lyons led the Knicks with 21 points, while Toney Douglas had 19 points and six assists.
Cartier Martin scored 24 points, and Kevin Palmer added 21 points and eight rebounds for Washington, which dropped its first Summer League game in five attempts.
