Dennis Smith Jr. will miss tonight's game with a left knee effusion.— Brad Townsend (@townbrad) October 20, 2017
The Mavs are calling Smith’s injury left knee effusion, which is swelling caused by fluid building up around the joint. It’s the same knee that Smith tore his ACL in during high school.
There is no timeline for Smith’s return, although it’s been reported on Twitter that Smith will also be missing tomorrow night’s game against the Houston Rockets, although nothing has been confirmed.
This is the second injury for Smith in the past week. He hurt his ankle in the second-to-last preseason game against Atlanta and then played the very next night in Charlotte. This is obviously way more serious.
For a potential origin of this injury, we have Austin Ngaruiya to thank as he pointed out Smith’s rough landing after trying to jam it hard during the season opener against the Hawks on Wednesday. Smith hobbled back to the locker room briefly before coming back out and finishing the game.
