Brooklyn Nets star guard Kyrie Irving said he would undergo an MRI after spraining his right knee. Irving left Saturday night’s 113-107 road loss to Washington in the fourth quarter, after getting tangled with the Wizards’ Bradley Beal and falling back awkwardly on the knee. “What a week,” Irving said. “I’m OK, though. Just gotta get an MRI. X-rays were negative, just [have to] go home and see what’s going on.”
