OKLAHOMA CITY -- It was a blow to the head that had the sports world buzzing Sunday.
The Thunder's James Harden suffered a concussion after Metta World Peace knocked him to the floor in a heated NBA battle against the Lakers.
Monday the Thunder said, "Harden participated in a series of limited activities per NBA guidelines, but has additional steps that must be taken under the league-mandated concussion policy before he can make his return to the court. "
They said he will be re-evaluated Tuesday and is currently listed as day-to-day.
Now, fans and medical professionals are weighing in on the incident.
Some saying the elbow to the head was intentional, while others disagree.
"There is no such thing as a truly trivial head injury, especially if you lose consciousness, have a concussion or are confused," OU Neurosurgeon Dr. Mike Sughrue said.
He said watching the game was upsetting because the injury has the potential to be a lot worse than people think.
"The patients I see who have this sort of problem often have more subtle problems that can be very debilitating for years that go on for years after the head injury," Dr. Sughrue said.
Thunder fans are lashing out against Metta World Peace.
The Sport's Animal's phones lit up all morning.
One caller said the hit was clearly on purpose and that it was done maliciously.
However, not everyone feels that way.
Former OU and NBA player, and now a Consulting Assistant Coach for the Sacramento Kings, Clifford Ray, said it wasn't a malicious act at all.
"They don't know who it is, they are just in the moment and I think he was just kind of coming out of that and clearing his way out of that," Ray said.
Clifford also said he has a feeling if the Lakers come to Oklahoma for another game, it could get ugly.
"They might throw cups at him, they are playing a seven-game series, you don't think the people of Oklahoma won't cheer if he falls or somebody trips him or knocks him down? What do you think they are going to do?"
