Celtics’ Irving day-to-day with strained right knee

Kyrie Irving of the Celtics has been diagnosed with a strained right knee.

Kyrie Irving’s injured right knee has been diagnosed as a strain and he is listed as day-to-day, according to the team.

The Boston Celtics’ All-Star point guard left a loss to the Los Angeles Clippers in the second quarter at TD Garden on Saturday night and did not return to the game. An MRI on Sunday revealed the strain.

The Celtics (35-21) have to games before the All-Star break, at Philadelphia on Tuesday night and Wednesday night against visiting Detroit.

After Irving left the game, the Clippers outscored the Celtics, 75-44, to erase a 28-point deficit and roll to a 123-112 triumph.

Irving, a six-time All-Star, did not play down the stretch in the regular season a year ago and missed the entire postseason after having surgery to remove two screws from the patella tendon in his left knee that were inserted in 2015 to repair a fracture that occurred while playing with the Cleveland Cavaliers against the Golden State Warriors in Game 1 of the NBA Finals.

He had surgery in Mach 2018 after a bacterial infection was discovered near the screws as a tension wire was removed. The screws were removed from a followup surgery in April.

Irving, 26, is averaging 23.6 points and career-highs in rebounds (4.9) and assists (6.9) in 32.5 minutes in 47 games this season, shooting a career-best 49.8 percent from the floor, 40.9 percent from long distance and 86.6 percent from the free-throw line.
