Doug Martin Entering 'Treatment Facility' ... I Need Help

Tampa Bay Bucs running back Doug Martin just announced he's entering a treatment facility after violating the league's drug policy.

Martin just issued a statement saying, "I was notified last week of a four-game suspension for violating the league's drug policy."

The 27-year-old did not reveal which substance he tested positive for though NFL Network's Ian Rapoport is reporting the substance in question is Adderall.

"My initial instinct was to appeal the suspension and finish the season with my teammates. However, after numerous discussions with people close to me -- including Coach Koetter -- I am starting the suspension immediately so I can enter a treatment facility and receive the help I truly need."

"On the field, I must be strong and determined to push through both pain and injuries to become an elite NFL running back. Off the field, I have tried that same approach in my personal life. My shortcomings in this area have taught me both that I cannot win these personal battles alone and that there is no shame in asking for help."

"I sincerely apologize to the Glazer family, General Manager Jason Licht and the entire Tampa Bay organization, my teammates and our tremendous fans. This was not the season I envisioned and I have let everyone down, including myself. However, adversity yields opportunity and I ask for your support in my battle to overcome these personal issues."

Martin fell off big time in 2016 after a stellar 2015 season in which he rushed for more than 1,400 yards.

He missed 6 games this season due to injury but even when he was healthy he didn't play well ... only averaging 2.9 yards per carry.
