The Chicago Bulls overcame the absence of a trio of injured starters and used their stifling defense to post an impressive 93-76 win at the Atlanta Hawks on Sunday.

Randy Foye scored 23 points for the Jazz, who led by as many as 10 points in the third quarter.
Cleveland’s Kyrie Irving put in a spectacular performance that led the Cavaliers to an unlikely 115-110 win over the Oklahoma City Thunder.

The severity of the injuries is not known, but Duncan did not return to the bench after being helped off the court by teammates.
Tony Parker scored 19 points and Danny Green added 15 for San Antonio, who have won 18 straight at home.
John Wall scored 21 points for Washington, who have lost 13 straight to San Antonio.

New York’s Amare Stoudemire was 10 for 10 from the field for 21 points, entering the game when the Knicks were trailing.
