The foul occurred when Brown tried to get a chase-down block on an Omri Casspi fastbreak layup attempt with the Kings trailing by 30 points. Brown's contact with Casspi sent the second-year Israeli forward to the floor.
A flagrant foul, category 1 penalty such as Brown was originally assigned would include a minimum fine of $1,000.
In recent weeks, several NBA players have been suspended for flagrant foul, category 2 penalties, including Philadelphia's Elton Brand, Portland's Andre Miller and the Los Angeles Clippers' Brian Cook.
