Ravens coach John Harbaugh confirmed Monday what the team feared when David Reed crumpled to the turf at M&T Bank Stadium without being hit by a Cleveland Browns player Saturday.

Reed tore the anterior cruciate ligament in his left knee during his 30-yard kickoff return to open the third quarter. It’s the second time in as many years that Reed will be unable to complete a season as he was shelved for the team’s final two regular-season contests and two postseason games last year by torn ligaments in his left wrist.

“David Reed has a torn ACL, isolated torn ACL,” Harbaugh said Monday. “So he’ll be out for the year, beginning his rehab as soon as he gets surgery, which has not been determined yet as far as the date on that.”

Reed had appeared to regain his status as the team’s primary kick returner before the injury, which was foretold when he grabbed his left knee after falling to the ground. Harbaugh predicted that if not for the injury, Reed would have turned that 30-yard return into a 99-yarder for a touchdown.

“I think it’s disappointing for David and for all of us because he was about to run that kick for a touchdown,” Harbaugh said. “That’s the thing that was probably the most amazing. He had two guys out in front of him, and I didn’t see anybody between him and the end zone. That was going to the house. Then the leg buckled. A lot of things are unpredictable in football. That’s certainly not one we would have predicted. We just have to move forward.”
