Perriman, who had already been ruled out for the game against the Cincinnati Bengals, pulled up while trying to run down a deep pass in the end zone. He limped afterward and didn't run any routes after that.
There was a brief conversation with a trainer, but Perriman remained on the field and caught passes while standing still. Before Perriman tweaked the injury, he was running close to full speed.
The No. 26 overall pick in this year's draft, Perriman returned to practice three days ago as a limited participant after missing eight weeks of practice. He sprained his right knee while catching a pass on the first day of training camp (July 30).
Without Perriman, Ravens wide receivers have caught 23 passes in the first two weeks, which ranks 19th in the league. Baltimore is one of three teams not to have a touchdown catch from a wide receiver (Kansas City and Minnesota are the others).
On Friday, coach John Harbaugh said Perriman was "getting close."
"But what that means exactly? I don’t know," Harbaugh said. "Nobody tells me. I have no report on it. I have no information on it because our medical people just don’t know. So, when they tell me he can play, he’ll be out there and play. It’s a tough injury to judge."
