Thunder guard Andre Roberson fell hard in the third quarter of Saturday's game vs. the Pistons while going up for an alley-oop, and remained down on the court for several minutes until a stretcher was brought out.

ESPN's Royce Young initially said Roberson had a "severe left leg injury" and those concerns turned out to be true. Before the game was even over, ESPN's Adrian Wojnarowski‏ reported, per a source, that Roberson had ruptured his patellar tendon. He also added, "There is still testing to do on Roberson to confirm full severity of leg injury."

Roberson's teammates looked on in anguish as the medical team worked on him. Roberson himself was seen with tears in his eyes, as he kept biting on a towel on his exit out of the arena.

LeBron James and Stephen Curry tweeted to Roberson shortly after the injury occurred.
