The Boston Celtics got quite a scare when Marcus Smart went down with what team officials determined to be dislocated right index and middle fingers.

Additional tests will be performed, but a source close to Smart told CSNNE.com that “he should be okay” and added that initial tests have the Celtics “almost 100 percent sure nothing” is broken.

The injury occurred in the first half of Boston’s matchup against the Portland Trail Blazers on Thursday night in the Las Vegas Summer League when Smart hit the floor hard along with Blazers forward and Haverhill, Mass. native Noah Vonleah while scrambling for a loose ball.

Smart gripped his hand quickly after he hit the floor, screaming in pain before the Celtics’ medical staff rushed on to the court to help Smart off and back to the locker room for X-rays.

However, Smart was able to return to the team’s bench before the game ended.

His return was good to see.

The fingers not being broken?

Even better.

The Celtics have made a conscious effort to get Smart as many reps as possible at the point guard position this summer.

And to his credit, Smart has stepped up to the challenge and has shown tangible growth in terms of his leadership and ability to balance being a scorer and distributor.

A lengthy hand injury would not only derail his progress, but potentially spill into training camp.

Smart was recently named to the Team World Roster that will play the first-ever NBA game in Africa next month, which will also include Brad Stevens as an assistant coach and teammate Evan Turner.

But with Smart's recent injury, even if it’s deemed not too serious, the Celtics will give serious thought to shutting him down the rest of Summer League in addition to him potentially not making the trip to Africa.
