OWINGS MILLS, Md. -- The Ravens are cautiously optimistic that wide receiver Breshad Perriman will return at some point during training camp after arthroscopic surgery on his left knee Tuesday revealed no significant damage to his ACL.
Coach John Harbaugh confirmed that Perriman doesn't need season-ending surgery after hurting his left knee last week and will need only treatment.
"He should be back at some point in time during training camp [and] certainly will be ready for the regular season," Harbaugh said. "But, again, that's always unpredictable. I think we've been down this road before."
Perriman, the No. 26 overall pick of the 2015 draft, was hurt catching the ball on a fade pattern in Thursday's offseason training activity, a source told ESPN. It was a noncontact injury. Perriman missed all of 2015 with a knee injury.
"Many, many strong prayers were answered on that," Harbaugh said after the team concluded the first session of a three-day mandatory minicamp.
Perriman was examined by Dr. James Andrews on Monday and underwent an arthroscopic procedure Tuesday that revealed he did not need reconstructive surgery. Instead, he received a stem-cell injection in the joint Tuesday, and the injury will be allowed to heal on its own.
Perriman will continue to receive treatment on his knee and undergo rehabilitation in the months ahead, with the target of returning to the field in late July or August.
On Friday, he complained of swelling around the knee, which led to an MRI and the diagnosis of some sort of ACL injury, as ESPN NFL Insider Adam Schefter first reported earlier Tuesday.
In 2015, Perriman hurt his right knee on the first day of training camp, which sidelined him eight weeks. He had been making progress in his return but then aggravated the knee again before a Week 3 matchup against the Cincinnati Bengals, hurting it while trying to catch up to an overthrown deep pass.
Perriman ultimately had surgery Oct. 1 to repair a partially torn posterior cruciate ligament. His absence was a blow for the Ravens, who had just one receiver, Kamar Aiken, catch more than 75 passes.
