Collins, who signed a one-year contract with the Bears in May, also will surrender an extra game check, the NFL ruled.
Per NFL rules, the reason for the violation was not disclosed.
Collins, however, was charged with marijuana possession in February after being arrested during a traffic stop in Virginia.
Collins, 24, appeared in 13 games over the past two seasons with the Jacksonville Jaguars. He has recorded 10 tackles and a half-sack.
