Marcus Smart's on-court scuffle with Trae Young is gonna cost him ... 'cause the NBA just fined the Boston Celtics player $25K as a result of the altercation.
The two guards got into it with 1:25 left in the game at State Farm Arena on Saturday ... when Young drove to the basket and got fouled by Smart.
It appeared Young may have accidentally kicked Smart in the groin during the play -- and Smart didn't like it one bit.
After the whistle was blown, Smart got into Young's face ... and the two exchanged some heated words.

That's when Smart and Young took their beef to the hardwood ... as Smart pulled the Hawks guard down with him as he fell to the floor.
Both players' teammates and referees broke them up ... and Smart was ejected from the game, while Young received a technical.
On Monday, an NBA executive announced that Smart -- the former NBA Defensive Player of the Year -- was fined $25K for "initiating an on-court alteration and pulling" Young to the floor.
As for Trae ... it seems he got away with just a tech.
The Celtics did win the game, however ... and are currently ranked 2nd in the Eastern Conference. The Hawks, on the other hand, are down in 8th.
