LeBron James said he would have his knee examined on Sunday evening as a precautionary measure.

James fell awkwardly to the court when going for an alley-oop in the Miami Heat's 99-93 win at the Knicks.

James appeared to hyperextend his left leg and then grabbed his knee.

“I was concerned,” James said. “I’m still concerned a little bit.”

James expected the knee to swell during the flight to Minnesota.
