WATCH: James Harden, Dejounte Murray have heated exchange

Rockets star James Harden was clearly frustrated early in Monday’s game, and it boiled over in a physical sequence with Dejounte Murray.

It was a first quarter to forget for Houston Rockets star James Harden on Monday, with the former MVP scoring just 2 points on 1-of-9 shooting.

However, it’ll likely be remembered for a while because of a confrontation he with Spurs guard Dejounte Murray.

Harden drove inside regularly and appeared to draw contact on several occasions, but officials didn’t grant him a single free throw in the quarter.

Harden’s frustration was evident in his body language on the court, and it boiled over in a physical altercation with Murray in which both players engaged in light shoving and were given technical fouls.

Some of Harden’s frustration may also have had to do with the opponent. The Rockets lost by two to the Spurs earlier this month in a game remembered for his dunk that didn’t count, and they were also denied their ensuing protest over that sequence.

In 20 games before the protest, Harden averaged 14.9 free-throw attempts per game. But the NBA’s scoring leader had a very different whistle in the six games since, averaging just 8.5 free throws per game.

The Rockets (17-9) fell behind 16-2 in the opening minutes of Monday’s game and trailed 35-21 after the first quarter, with Harden’s sub-standard contributions a key early storyline.
