ANALYSIS: This is a devastating blow for Philadelphia, at least in the short-term, as the team tries to put away its first round series against the Wizards. Embiid left during Game 4 after scoring eight points, and the Sixers ultimately lost 122-114 in Washington. Philly takes a 3-1 series lead back home Wednesday.
