Mario Chalmers of the NBA's Miami Heat committed his second flagrant-2 foul of the season in the team's win over the Dallas Mavericks, and has been suspended for one game as a result.

Dallas' Dirk Nowitzki took a shot to the head from Chalmers as the Miami guard came off a screen during the fourth quarter. Chalmers was ejected from the game when the foul was ruled a flagrant-2 after review. It was the second this month for Chalmers, as he hit Blake Griffin in the same type of play in a win over the Los Angeles Clippers.

According to ESPN, Chalmers will be fined $15,000 for the hit.

Chalmers claimed it was not intentional, and that he was trying to get his arm free from Dallas' Samuel Dalembert.

"Dalembert had my arm so I had to get my arm free," Chalmers said. "There was nothing intentional about it. I didn't even see Dirk."

HoopsWorld.com reports that Chalmers will serve his one-game suspension on Saturday when Miami visits the Charlotte Bobcats.
