The Browns will be without middle linebacker Joe Schobert for the foreseeable future because of a hamstring injury, coach Hue Jackson said.
"He'll be down for a little while, how long that will be, we'll see how that will all unfold," Jackson said Monday.
Schobert suffered the injury in the third quarter of Sunday's 38-14 loss to the Chargers and did not return. Before that, the third-year player had played every single defensive snap this season.
Jackson, who doesn't believe that workload caused the injury, said the team will have discussions about how to best move forward without Schobert. His backup, James Burgess, also left Sunday's game with a hamstring injury and could miss time, Jackson said.
"We're going to talk through that this evening," Jackson said. "We'll have some answers there. We feel good that we'll still put a good defense out there."
Schobert had 49 tackles, 1.5 sacks and an interception in six games. He led the team with 144 tackles in 2017 and earned Pro Bowl honors.
