The Ravens have placed running back Danny Woodhead on injured reserve with a hamstring) injury. To take his place on the 53-man roster, the Ravens have promoted Jeremy Langford from the practice squad. 
The Ravens initially thought they would be without Woodhead for 4-6 weeks. Unfortunately, further tests showed that his condition was worse than initially thought. He’s now facing a 6-8 week timetable, meaning that the Ravens were essentially forced to clear out his roster spot. Per league rules, Woodhead can become one of two players to return from IR for the Ravens, but he’ll first have to sit out for a full eight weeks.
Woodhead joined the Ravens on a three-year, $8.8MM deal with $4.25MM guaranteed back in March. It was a surprisingly large investment considering Woodhead’s age, injury troubles in 2016, and how weak the RB market has been.
A former fourth-round pick, Langford rushed for 537 yards and six touchdowns as a rookie with the Bears. At one point it looked like his future was bright in Chicago, but he was displaced from the roster altogether in early September. The Bears cut Langford in favor of UDFA Taquan Mizzell, who ironically was released by the Ravens. In 2016, he had only 62 carries in 12 games.
