Boston Celtics head coach Brad Stevens says star point guard Kyrie Irving didn't make the trip to Philadelphia and that he hasn't been told anything definitive yet on Irving's knee.

Kyrie suffered a strained right knee on Feb. 9 against the Los Angeles Clippers and was forced to exit the game.

The Celtics have to play it safe with Kyrie Irving since he has an extensive injury history. The hope in Boston is that Irving doesn't have any structural damage in his right knee.

In 47 games this season for Boston, Irving is averaging 23.6 points, 4.9 rebounds and 6.9 assists per contest. “Uncle Drew” is shooting 49.8 percent from the field, 40.9 percent from beyond the arc and 86.6 percent from the free-throw line.

Irving has 14 double-doubles on the season. Boston is 28-19 when Kyrie plays.

The good news is that Irving is dealing with a right knee injury and not a left knee ailment.

The All-Star guard underwent season-ending surgery on his left knee last season. Irving also suffered a fractured knee cap in his left knee back in 2015 when he was still with the Cleveland Cavaliers.

Let's hope that Irving isn't out for an extended period of time.

The Celtics need their floor general back on the court.
