Denver Nuggets superstar Jamal Murray tore up his knee in such a scary fashion Monday night ... even the game's broadcasters were having trouble watching a replay of the injury.
"This is awful," one said ... while another added, "He's in a lot of pain. I don't even know if I want to watch this."
The gruesome play all went down in the final minute of the Nuggets' loss to the Warriors ... when Murray was driving to the basket at full speed.
