The Lakers trailed the Mavericks 21-11 with 5:16 remaining in the opening frame during the sequence on Friday at Staples Center in Los Angeles. James ran under the basket and received a pass on the baseline. He tried to put up a shot with his back to the basket, but Doncic jumped up and blocked the attempt.
James caught the ball and immediately went up for another shot, but the rookie got another rejection on the "King."
The Mavericks then took off with the ball in transition.

"He actually came out of nowhere to get the double block on me," James told reporters. "It wasn't even his man he covered for. I told him 'I didn't even see you on both attempts."
Los Angeles ended up with a 114-103 victory. James had 28 points, five rebounds and four assists in the win. Doncic had six points, six rebounds, five assists, three steals and two blocks for the Mavericks. Harrison Barnes led all scorers with 29 points for Dallas.
The Lakers host the Phoenix Suns at 3:30 p.m. on Sunday at Staples Center.
