OKC duo Westbrook, Durant fined after fiery win in game four

The Oklahoma City Thunder are up big in their NBA play-off series, but star duo Russell Westbrook and Kevin Durant just took a big hit in their wallets.

Westbrook and Durant were both fined by the NBA for separate incidents that occurred during the Thunder’s 119-108 win over the Dallas Mavericks on Saturday, the league announced on Sunday.

Westbrook was fined $25,000 for directing inappropriate language at a fan.

Durant was hit with a $15,000 fine for his Flagrant 2 foul against Mavs forward Justin Anderson with less than a minute remaining in the game.

The Thunder hold a 3-1 lead over the Mavs in their Western Conference first-round series.
