The response to that question is accompanied by an amorphous storm cloud of uncertainty.
Perriman missed his entire rookie season with perpetual knee issues. The former first-round pick was again sidelined June 11 when he suffered a partially torn ACL during OTAs.
Perriman is running Harbaugh said, but despite mid-August being targeted for a return, it sounds as if the wideout will continue to miss time.
"He's on the ground running right now, but I haven't been told that he's going to be back to practice, tomorrow," Harbaugh said. "I'm just like the fans. I'm waiting for him to get back out there, and when he's ready he'll be back out there."
Even if the 22-year-old returns before Week 1, it's unlikely he'll play a big role in the Ravens' offense from the jump, given he's spent more than a year off the football field.
