Jared Sullinger flails backwards while defending Dwight Howard.Boston Celtics forward Jared Sullinger received a warning for violating the league's anti-flopping rule during Tuesday's loss to the Houston Rockets.

Midway through the second quarter, Sullinger flailed backward under the basket while battling for position with Houston's Dwight Howard. Referees whistled Howard for an offensive foul resulting in a turnover.

The NBA issues a flop warning for a first violation, while fines ramp up by $5,000 for each additional violation ($5,000 for second violation; $10,000 for third violation).

The NBA flopping rule was initiated last season and states that players may not commit any physical act that, following review, reasonably appears to be intended to cause the game officials to call a foul on another player.

This is the Celtics' first flop warning of the season.
