J.J. Barea of the Minnesota Timberwolves and Donald Sloan of the Cleveland Cavaliers have received official warnings from the NBA for flopping.

With 10:04 remaining in the fourth quarter of the Wolves' 92-80 victory over the Sacramento Kings on Friday, Barea committed an acting job while guarding the Kings' Jimmer Fredette that caught the league's eye. Meanwhile, Sloan's violation came at the 5:58 mark in the fourth quarter of the Cavs' 115-86 loss to the Chicago Bulls on Friday. Sloan made slight incidental contact with the Bulls' Kirk Hinrich, and proceeded to spin around and hit the floor.

Prior to the start of the season, the NBA put a rule in place to limit the incessant amount of flopping that has surfaced in recent years. The first violation results in a warning, but players who commit additional violations beyond that will be forced to pay a fine, starting with $5,000 for the second violation and increasing to $30,000 for a fifth incident.
