The Ravens placed tight end Dennis Pitta and free safety Terrence Brooks on the physically unable to perform list, an unsurprising development considering the severity and timing of their respective injuries.
And undrafted rookie offensive lineman Leon Brown passed his physical and was cleared to practice.
Pitta has rehabilitated his surgically repaired right hip after fracturing and dislocating it for a second time last September. However, it remains unclear if he'll be medically cleared to play again. Pitta is likely to begin the regular season on the reserve list and would be required under NFL rules to miss at least the first six games of the regular season.
Pitta hasn't been medically cleared to practice since his second major hip injury in the past two years.
Pitta initially fractured and dislocated his hip in 2013 during training camp when he fell awkwardly while trying to make a contested catch against strong safety James Ihedigbo.
Signed to a five-year, $32 million contract that includes $16 million guaranteed, Pitta is due $4 million this season regardless of whether he's able to play.
Pitta had surgery last September after getting hurt against the Cleveland Browns when he caught a pass and planted and injured his hip again without being hit.
Meanwhile, Brooks has been practicing without setbacks and even participated in full-team drills after tearing his anterior cruciate ligament and medial collateral ligament against the Jacksonville Jaguars last December.
He's far ahead of schedule in his recovery.
"I'm breaking on the ball and little stuff like that, but that's got to get better," Brooks told The Baltimore Sun in minicamp. "But that comes with more rehab and getting a little stronger. Everything else feels pretty good.
"I definitely don't feel like I'm rushing. It's not like I'm hurting myself while I'm doing it. I'm pushing myself. It really feels good."
Brooks was drafted in the third round last year out of Florida State and finished with 19 tackles, two passes defended and a fumble recovery in 11 games.
Although Brooks didn't start a game as a rookie he displayed potential. He delivered a concussion-causing hit when he blasted Tennessee Titans tight end Delanie Walker. He was also benched after allowing a long touchdown pass to wide receiver Marques Colston against the New Orleans Saints.
Brooks could bolster the Ravens' depth at free safety behind newly acquired starter Kendrick Lewis, a former Houston Texans and Kansas City Chiefs starter who was signed to a three-year, $5.4 million contract this offseason.
For Brooks to contribute this season, he'll need to regain the last remaining element in his recovery from a major knee injury.
"Explosiveness, explosion, I can definitely feel the difference from the explosion I had before and how fast I can get to places and close on the ball," Brooks said. "I can definitely feel the difference, but I don't get down about that. I'm under six months and I'm practicing, so I can't feel too greedy."
Brooks hasn't ruled out the possibility of playing sooner than anticipated and being ready for the first game of the regular season.
"It's definitely a possibility, but it's up to the trainers," Brooks said. "I have to trust it and prove I can actually go out there and compete. I definitely don't want to go out there and be a step slower or a couple of steps slower.
"I want to be able to compete at a high level. I put in the hard work and it benefits you. Everybody has been praying and helping me get through it."
