The NBA has issued flop warnings to Brandon Jennings and Taj Gibson of the Detroit Pistons and Chicago Bulls, respectively.
Jennings flopped twice in quick succession against the Houston Rockets and will now receive a $5,000 fine if found guilty of another flopping violation.
Gibson will face the same punishment if he commits another flopping offence after his play-acting in the first quarter of the Bulls' 100-84 victory over the Cleveland Cavaliers.
The NBA are keen to stamp flopping out of the sport and have issued similar warnings to other players in past months.
James Harden of the Houston Rockets was fined $5,000 in November - the first player of the season to receive a financial punishment - after two flopping violations.
Other players who have been warned this season include Chris Paul of the Los Angeles Clippers and the Washington Wizards' John Wall.
