<p>PHILADELPHIA &mdash; Philadelphia 76ers center Joel Embiid is doubtful for Game 5 because of a sore right knee.</p>
<p>Embiid had an MRI on Tuesday and his status will be decided before Game 5 of Philadelphia’s game against the Washington Wizards, a person familiar with the decision told The Associated Press. </p>
<p>The person spoke to The AP on Tuesday on condition of anonymity because the decision was not made official.</p>
<p>The Sixers lead the Wizards 3-1 in the first-round Eastern Conference series. Game 5 is Wednesday night.</p>
<p>The NBA MVP finalist wound up on the floor behind the baseline after having his shot blocked by Washington’s Robin Lopez on a drive to the basket in the first quarter. </p>
<p>After staying down for a moment, a wincing Embiid rose and then put his hand on his lower right back.</p>
<p>He remained in the game for the time being, before eventually heading to the locker room in the last minute of the period.</p>
<p>Embiid came into the game averaging more than a point per minute in the best-of-seven series.</p>
<p>He scored a postseason career-high 36 points in 28 minutes in a 29-point win for the 76ers in Game 3 on Saturday.</p>
