Oklahoma City Thunder guard Andre Roberson took a nasty fall on Saturday going up for an alley-oop, and he had to be taken off the court on a stretcher afterwards.

The fall occurred late in the third quarter of the team’s game against the Detroit Pistons.

Here’s a couple of looks at the tumble.

ESPN’s Royce Young believes it’s a “severe left leg injury.”

Roberson is a very solid role player who averages five points and 4.7 rebounds per game for the Thunder.
