The Cavs announced J.R. Smith has been suspended one game for detrimental conduct and will serve it Thursday night against the Philadelphia 76ers at Quicken Loans Arena.

Cavs coach Tyronn Lue said Rodney Hood will start in place of Smith and Jeff Green will also be available after missing Tuesday's game with lower back soreness.

Lue would not give details about what prompted the suspension, but said it happened after shootaround, which Smith attended. Lue said Smith would regain his starting spot when the Cavs host the Denver Nuggets on Saturday night.

"He was great this morning," Lue said. "Something happened after shootaround, so, thatís all the details Iím going to give to you. Heíll be ready for tomorrow and be ready to go on Saturday."

Smith has started 56 of the Cavs' 59 games this season and is averaging 8.3 points, 3 rebounds and 1.9 assists in 29.3 minutes.

Smith did not play in the fourth quarter of Tuesday night's home victory over the Brooklyn Nets. He scored four points on 2 of 9 field goals, 0 for 3 from long range, in 22 minutes.

Lue has stuck with Smith through a rocky 1 1/2 seasons because Lue felt the Cavs wouldn't have won the 2016 NBA title without Smith's crucial third-quarter scoring in Game 7 against the Golden State Warriors. Smith has started 213 of 223 games since he was traded to Cleveland from the New York Knicks in a three-team deal on Jan. 5, 2015.
