Irving sat out the fourth quarter of Thursday night's home victory over the Utah Jazz with stiffness in his left knee, so it made sense for him to sit, Lue said.
Cleveland Cavaliers point guard Kyrie Irving (knee tightness) will undergo treatment on his knee and has said that he is "hoping" that he will not be forced to miss any time.
Last week's highly-anticipated game between the San Antonio Spurs and Golden State Warriors did not include Kevin Durant due to a knee injury along with Stephen Curry and Klay Thompson, who were resting.
James had 10 rebounds with six assists.
The Cavaliers can thank their lucky stars they still have a healthy four-time NBA MVP LeBron James, who was more than happy to pick up the slack.
Irving had 21 points and Shumpert 9. He is on a minutes' restriction and has not been cleared to play on consecutive nights.
J.R. Smith's 3-pointer late in the first quarter was the 881st of the season for the Cavs, shattering the previous franchise record for makes from downtown in a single season set past year, yet there are still 15 games left on the schedule. They shot 57.5 % while recording a season-series sweep of Orlando and an eighth straight win overall against the Magic.
