Suspended Browns receiver Josh Gordon might be in trouble with the NFL again.
A person familiar with the situation tells The Associated Press that Gordon has "raised a red flag" because of a recent league-administered drug test. The person, who spoke on condition of anonymity because results of NFL drug tests are not made public, says Gordon didn't have a positive substance abuse test.
But a sample collected in March showed Gordon had traces of marijuana and a diluting substance in his system. The level of marijuana was less than the minimum required by the NFL for a positive test.
