NBA Star Jamal Murray Gruesomely Injures Knee In Game, 'This Is Awful'

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.

You can see in clips of the play, as Murray planted his left leg to try to explode upward ... his knee just simply gave out on him.

The 24-year-old -- who had a breakout season last year and helped lead Denver to a Western Conference Finals appearance -- immediately crumpled to the hardwood in pain.

He let out several screams, pounded the floor ... and needed several trainers to help him get up.

A wheelchair was ultimately brought out for Murray ... but he refused to get in it -- and instead, hobbled off the floor and into the locker room.

The severity of Murray's injury was not yet known immediately after the game -- he'll undergo further testing Tuesday -- but it was clear to all involved it could be a devastating one for the Nuggets' star.

"Keep Jamal in your thoughts and prayers," Denver head coach Michael Malone said, "and hopefully we'll get some good news."

Added Warriors head coach Steve Kerr, "We hope he's not injured, that was a really scary fall and there was silence in the gym. Everybody is so concerned for him, so fingers crossed."

Steph Curry, who was just feet away from Murray when he suffered the scary fall, said he, too, was hoping Murray avoided catastrophic knee damage.

"My heart goes out to him," Curry said. "I hope that he gets the best news possible."

Murray had averaged 21.2 points per game this season ... and helped Denver to a 34-20 record. Most believed with a healthy Murray, the Nuggets had a great chance to win the Western Conference.
