Ravens coach John Harbaugh downplayed the severity of the injury.
"Ed Dickson, his hamstring grabbed a little bit, so we pulled him out for precautionary reasons," Harbaugh said. "We'll take a look at it [Sunday] and see how it looks."
Meanwhile, starting strong safety James Ihedigbo didn't practice at all due to a strained neck with wide receiver David Reed sidelined with a tweaked groin.
"We're just giving James a rest on the neck," Harbaugh said. "He kind of tweaked it a little bit, a little strain in there. In those special-teams drills, he goes pretty hard there. I wanted to back him off a little bit. Nothing serious with David. I think he had a little bit of a groin, just resting him."
