PHILADELPHIA -- Cavaliers guard J.R. Smith missed shootaround Monday morning after learning of a death in his family, a source told cleveland.com.

The source, who is close to Smith, said he expects to play against the Philadelphia 76ers.

But a cousin to Smith died Sunday night and the Cavs guard learned about it Monday as the team was getting ready for its workout.

Cavs rookie Cedi Osman participated in the team's morning walkthrough with the starters.

Smith is averaging 7.8 points per game and shooting .308 from 3-point range this season. He scored 16 points in Cleveland's 100-99 win over Charlotte on Friday.
