Alonzo Gee's putback with less than a second remaining gave The Cavaliers a 113-111 win at Atlanta on Friday.
It also snapped a four-game losing streak and gave Cleveland just its second win in six games since Kyrie Irving fractured a finger Nov. 18. They had lost 10 of 11 prior to Friday.
With the slumping Trail Blazers heading to Quicken Loan Arena Saturday, The Cavaliers could find themselves on a two-game winning streak despite Irving likely to be out until the third week of December. He was seen going through a shooting drill last week, but his finger was still heavily bandaged.
Cleveland (4-12) is trying to tread water with Dion Waiters' 15.4 points a game and Anderson Varejao's NBA-leading 15.1 rebounds a game, but they're still last in the Central division, a half game behind Detroit.
Tip-off is scheduled for 7:30 p.m. ET from Quicken Loans Arena in Cleveland. TV broadcast is on FOX Sports Ohio with 1100 AM WTAM on the radio broadcast.
