Baltimore Ravens defensive tackle, suspended for the final four games of the season, was using Adderall "due to a lack of sleep while helping his wife with their three children," the Baltimore Sun's Aaron Wilson reported.

The drug, commonly used for conditions like ADHD, is allowed when players submit proper documentation and have their use cleared by the NFL. But Ngata was apparently using it on his own, if the Sun's source is accurate, as a means of keeping his energy up around the house.

Rules are rules and Ngata surely knew the consequences of taking prescription pills without clearance, but if true, this information at least takes a bit of the negative light away from his suspension.

Either way, the Ravens will be moving on and replacing Ngata in the lineup. More on that here.
