Pittsburgh Steelers running back DeAngelo Williams underwent knee surgery on Wednesday, and is without a date for a return, reports DKPittsburghSports.com.
Williams will be out for "up to a month." He's been strictly a handcuff for Le'Veon Bell owners, so those duties will now be handed to Fitzgerald Toussaint.
The Steelers rank seventh in the league in Adjusted Rushing Net Expected Points per play this season.
