Smith has started 213 of 223 games played for the Cavs since he was acquired from the New York Knicks in a three-team trade on January 5, 2015.
The soup toss came following Thursday's shootaround at the team's training facility, hours before the Cavs played the Philadelphia 76ers, a person with direct knowledge of the situation told The Associated Press on Friday.
At first, the specifics of Smith's suspension were somewhat mysterious. Cavs head coach Tyronn Lue said "something happened after shootaround" which prompted the team to dish out the punishment.More news: Nirav Modi fraud: CBI arrests auditor of PNB
An explanation of what pushed J.R. Smith over the edge, or at the very least a public apology, will have to wait another day. He's always been a streaky shooter, but his shot isn't falling as often.
Smith is averaging 8.3 points and 1.9 assists in 59 games (56 starts) this season.
The timing could not have been worse for Smith, whose decline in minutes can be attributed to trade deadline acquisitions such as Hood as well as guards Jordan Clarkson and George Hill.
"Jones, a former Cavs player, has been back with the organization since 2014". Smith is set to return to practice Friday, according to ESPN.
