Kyrie Irving will miss at least a week with a sprained medial ligament in his right knee. The Brooklyn Nets star had an MRI exam that confirmed the team's diagnosis after Irving was injured Saturday in Washington. He was hurt in the fourth quarter of a 113-107 loss, when he and Wizards guard Bradley Beal got tangled battling for a loose ball and Irving's knee twisted as he landed on the court. Irving had his highest-scoring game of the season the previous night, scoring 54 points in a victory over Chicago. The Nets said Irving will be re-evaluated in a week.
