Andre Drummond remained in full uniform more than a half hour after the Detroit Pistons' loss to the Houston Rockets working on his free throw shooting.

Drummond went 1-for-6 at the line in the loss and missed a pair of free throws with 4.6 seconds remaining in the game with a chance to tie.

Drummond is shooting 51 percent from the free-throw line but has struggled of late, going 3 for 12 in the last two games and 4 for 16 in the last six.

Drummond shot an NBA-worst 35.5 percent from the lane in 2015-16.
