Kyrie Irving has been diagnosed with a strained right knee after an MRI in Boston, the team announced Sunday. The Celtics guard is listed as day-to-day.

Irving suffered the injury with about five minutes left in the second quarter of Saturday night's game against the Clippers. The Clippers outscored the Celtics 75-44 after Irving left, coming back from 28 points down to win 123-112.

Irving missed the end of last season and the playoffs after having surgery on his left knee to remove two screws from his patella that were inserted in 2015 to repair a fracture he suffered during that year's NBA Finals.
