Ravens coach John Harbaugh said starting left guard Alex Lewis is dealing with a concussion suffered in the fourth quarter of Sunday's 19-17 win against the Jacksonville Jaguars.
"Alex is in the concussion protocol right now," Harbaugh said Monday. "So we'll just have to see how that goes."
The 6-foot-6, 315-pound Lewis, the organization's third of five picks in the fourth round of the 2016 NFL draft, has made all three starts at left guard. He played 57 offensive snaps Sunday. But he sustained the concussion sometime during the final period and was replaced by 6-4, 310-pound Ryan Jensen.
Jensen, who played the last 10 snaps and could be in line to start Sunday against the Oakland Raiders if Lewis is unavailable, drew praise from Harbaugh.
"I thought he played well," he said. "Ryan goes out there, and he always gives you a spark. He played really well. He was physical and played well. That's one thing, one of the things we feel really good about. We've got some depth in our interior offensive line."
