Frank Vogel and LeBron James expressed their frustration after James did not go to the foul line during the Los Angeles Lakers' 109-108 win over the Memphis Grizzlies.
James, who finished with 30 points, took 27 field goals without getting fouled.
"I'm living in the paint and if you look at my arm right here, these are four or five [scratches] that happened the last two games, and they weren't called at all," said James.
James is averaging 5.6 free throws per game this season, the lowest of his career.
"It's frustrating. LeBron's going to the basket all night long. He took nine 3s, but he's in the paint all night long. ... We'll deal with the proper channels and talk to the league about that," added Vogel.
