The NBA is looking into allegations that the Knicks circumvented league rules by conducting secret workouts with college players.

Teams are not supposed to work out players before the annual predraft camp and can only conduct a certain number of workouts.

Knicks director of East Coast scouting Rodney Heard held workouts in gymnasiums in the Atlanta area in violation of league rules, according to a Yahoo! Sports rule.

"We will be investigating these allegations," NBA spokesman Tim Frank said Tuesday.

The Knicks said in a statement that they are cooperating with the NBA and "defer all comment to them."

One incident occurred in May 2007 when Kansas guard Brandon Rush suffered a serious knee injury. He later withdrew from the draft.
