Baltimore Ravens running back Kenneth Dixon has been suspended for the first four games of the 2017 season after violating the league's policy on performance-enhancing drugs, the NFL announced Thursday.
Dixon, a fourth-round pick in 2016, had a promising rookie season in which he ran for 382 yards and two touchdowns. He was expected to compete against Terrance West for the starting running back job this season.
In a statement released by the team, Dixon apologized to the organization and its fans.
"I mistakenly took a substance without the proper NFL medical exemption, and while it was unintentional, I accept full responsibility for my actions and their consequences," Dixon said. "I am truly sorry for the mistake I made and the distraction it causes. Moving forward, I remain committed to focusing on my offseason training, conditioning and game preparation so I can be an immediate impact player for the Ravens when my suspension is over."
The Ravens signed former Chargers running back Danny Woodhead to a three-year deal on Thursday. Coach John Harbaugh previously said he wanted to add a big-play running back, which could happen in the draft.
The 134th overall pick in 2016, Dixon starred at Louisiana Tech and finished second in NCAA history with 87 touchdowns.
Dixon is eligible to participate in all offseason and preseason practices and games.
"While we are disappointed in the mistake Kenneth made, we appreciate the fact that he has assumed responsibility for his actions," general manager Ozzie Newsome said in a statement. "Kenneth is a good person, but he must learn from this and take the proper steps to rebuild trust within the organization, especially with his coaches and teammates."
