The Bears expect running back Jeremy Langford to be sidelined for 4-6 weeks with sprained ankle, a source tells Adam Schefter of ESPN.com (on Twitter). 
Langford, an NFL sophomore, was thrust into the starting role this season following the departure of Matt Forte. Through three games this season, Langford has amassed 116 yards off of 31 carries with two touchdowns. His 3.7 yards-per-carry average has been roughly in line with his 3.6 ypc posting last season.
With Langford sidelined for multiple weeks, the Bears will likely turn to Jordan Howard, a fifth-round pick out of Indiana. “The Bulldozer” has looked sharp in a limited sample size, posting a 5.6 ypc average off of 12 attempts. The Bears also have Ka’Deem Carey on the depth chart, but he is dealing with an injury of his own.
