Here's some news fans of the Philadelphia 76ers might not want to hear: Joel Embiid has been dealing with knee soreness for the last few weeks, and head coach Brett Brown has known about it.

There is no structural damage in the knee, which is good news, but any type of knee problems involving Embiid are concerning. Throw in the fact that Brown has known about it for weeks, and that Embiid played in the All-Star Game, and fans have a right to be a little miffed.

The Sixers have done a good job of building a starting five that can compete with any team in the NBA. In doing so, they haven't been able to put together much depth. Losing their best player and only true banger down low could create some problems if he misses extended time.

Losing Embiid for a long time would be the biggest possible blow the Sixers could be dealt. Playing this safe now is the smartest thing they can do, though it seems they should have been a bit safer before this.

Hopefully, everything works out well for Joel Embiid and the Sixers, as this season was shaping up to be a fun one in the Eastern Conference. If not, fans will be left wondering what could have been if Brown and Embiid took the soreness more seriously and played it accordingly.
