VIDEO: Clippers' Pierce shoves Green in the back, issued flagrant 1

A flagrant 1 foul is defined by the National Basketball Association as "unnecessary contact committed by a player against an opponent."

That just about sums up Paul Pierce's actions Monday night against Jeff Green of the Memphis Grizzlies.

With Green going up for a layup, "The Truth" came from behind and shoved him in the back, sending the 29-year-old flying.

The Los Angeles Clippers veteran seemed remorseful after the play, immediately going to Green seemingly to admit his fault.

Pierce's flagrant foul was the seventh issued to begin the 2015-16 season. He led the NBA last season with three.
