Doug Martin suspended four games, entering rehab

Tampa Bay running back Doug Martin has been suspended four games for violating the NFL’s policy on performance enhancing substances and said Wednesday he’s entering a treatment facility rather than appeal the ban. "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. The 27-year-old signed a five-year, $35.75 million contract, with $15 million guaranteed, in the offseason after finishing second in the NFL in rushing in 2015 with 1,402 yards.
