TAMPA, Fla. (AP) — 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.
"Doug has been a valued member of our organization for the past five seasons and we respect and support his decision to seek help,Cheap Jerseys," Bucs general manager Jason Licht said.
Afterward, Koetter declined to comment on his situation, saying a statement from the player would be forthcoming.
Martin said in a statement that he learned of the suspension last week and that his "initial instinct" was to "appeal the suspension and finish the season with my teammates."
Although, the two-time 1,000-yard rusher never regained the form that helped him finish second in the league in rushing behind Adrian Peterson last season, the Bucs rattled off five consecutive victories — beginning with a 26-point win over Chicago — to climb into contention for the club's first playoff berth since 2007.
The fifth-year pro said he decided to enter a treatment facility "and receive the help I truly need" after discussing the matter with people close to him, including Bucs coach Dirk Koetter.
He finished with a team-leading three rushing touchdowns,Wholesale Jerseys Online, however his yards per attempt average is the lowest among NFL runners with at least 100 carries.

The 27-year-old running back was excused from practice Wednesday.
"Off the field, I have tried that same approach in my personal life," Martin said in the statement released through the team. "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."
He also sat out last week's 31-24 loss at New Orleans after being declared inactive against the Saints, though that game won't count against the penalty.
