Ravens DE Derek Wolfe likely out for rest of season

The Baltimore Ravens have encountered yet another injury setback as they prepare to play at the Chicago Bears this coming Sunday. 

According to Ryan Mink of the club's website, Baltimore defensive end Derek Wolfe is expected to remain sidelined for the rest of the season. The 31-year-old suffered what have been referred to as back and hip injuries during joint practices with the Carolina Panthers in August and hasn't taken the field since. 

Per Jamison Hensley of ESPN, Wolfe's 21-day practice window expires Tuesday. At that point, Baltimore will have to either elevate him to the active roster or keep him on injured reserve until next season. 

"That's not going to be looking good this year. I think Derek's going to be out for the rest of the year in all honesty – it looks that way" head coach John Harbaugh said on Monday. "I don't really have any details on it. I can't say that I understand it completely."

Harbaugh didn't get into specifics about Wolfe's condition or confirm if he suffered a setback during his brief appearance in practice last month before Baltimore's bye. 

"He's not in a place where he's going to be able to play," Harbaugh added. 

Justin Madubuike has replaced Wolfe, who becomes Baltimore's sixth starter ruled out for the remainder of the campaign, in the lineup. Madubuike has 16 total tackles and a single sack this season.
