LeBron James will undergo an MRI on Wednesday to determine the severity of his left groin injury.

The initial feeling is positive, with James "in good spirits" in the locker room after the Los Angeles Lakers' impressive 127-101 win over the Golden State Warriors.

James was hurt in the third quarter when he said he "overextended" his groin as his right leg slipped.

"The good thing is the muscle is intact."

"With me with injuries, I am never too concerned about them," said James, who had an electric stimulation device attached to his hip before he and the Lakers flew back to Los Angeles. "I was able to walk off on my own power. I felt a pop and see if I could stretch it a few times and see if it will relieve, but it didn't."
