An MRI taken Monday on rookie wide receiver Breshad Perriman's knee revealed no additional damage.
Perriman has been sidelined since hurting his knee in the Ravens' first full-team training camp practice on July 30. His knee hasn't responded as quickly as team officials had hoped, which is why he was sent for an MRI.
"It came back essentially normal," Ravens head coach John Harbaugh said following Tuesday's practice. "It's just gone slower that our doctors anticipated it would. So we wanted to get an MRI to see if there's something we didn't know about and there wasn't. It's normal. There's just still a little bit of swelling, still a little bit of a sprain. That's what they call it. We're just going to keep working on it."
All in all, team officials considered the MRI results positive. However, it's still unclear when the first-round NFL draft pick will return to the practice field. He certainly won't return for the team's joint practices with the Philadelphia Eagles later this week or play in the team's preseason game against the Eagles on Saturday.
Harbaugh initially called Perriman's injury a bruise, but has since said Perriman has a strain and tendon damage. However, Harbaugh said last Saturday that he remains confident that Perriman will return at some point this preseason.
Perriman's absence, along with Marlon Brown's hamstring and back injuries, have made it tough for the Ravens to evaluate the wide receiver competition.
"It's not a challenge not having Breshad; that's not really the issue," offensive coordinator Marc Trestman said Monday. "We're disappointed for him, No. 1, that he can't be out there to work, and there's nothing we can do [about] it.
"So, we have to turn it into a positive, and the guys do so by understanding they have a great opportunity here to have another rep, another opportunity. And we've got to continue to work to develop the guys we're with, and that's the positive side of it."
