Ravens linebacker Elvis Dumervil will miss his fourth game of the season on Sunday against the Giants, and coach John Harbaugh on Friday expressed concerns about the Pro Bowl linebacker going forward.
Dumervil was declared out for Sunday's game, one of 11 players on a lengthy Ravens injury report that featured four starters listed as doubtful.
Dumervil missed almost all of training camp and then the first three games while recovering from offseason foot surgery. He returned to action for the past two games against the Raiders and Redskins.
But "that explosiveness really wasn't there," Harbaugh said on Friday, "and he wasn't really able to get into a tackle and push like he needs to."
In limited action -- Dumervil played 20 snaps against the Raiders and 25 against the Redskins -- Dumervil has had little impact, with no tackles or sacks. Dumervil, 32, set a Ravens franchise record with 17 sacks in 2014.
The Ravens overall have struggled to generate pressure on the quarterback from their outside linebackers. Through five games, the Ravens have 10 sacks, with four from Terrell Suggs and six from defensive linemen.
Dumervil did not practice this week and was not available in the locker room this week when media were present.
Harbaugh said he did not view Dumervil's injury as a season-ender or "he'd be on (injured reserve)."
After Sunday's game against the Giants and next week's game against the New York Jets, the Ravens have their bye week, which would give Dumervil an additional week to heal.
"Definitely, we're hoping to get him back sooner rather than later," Harbaugh said. "When will that be? I'm hoping sooner. We'll see, but it's a strength issue in his foot and his ankle. It's got to be right."
