Both players worked separately off to the side with trainers during the 30-minute portion of practice the media was allowed to watch.
"I'm hopeful that both will play," coach Rex Ryan said. "I would think that Cro is probably ahead of Nick, but I'm hopeful both will play. I'm not really sure, though."
Mangold missed the Jets' 34-24 loss at Oakland last Sunday with a high right ankle sprain suffered the previous week against Jacksonville but has recovered quickly. He is walking around without any sign of a limp, although the ankle is still heavily wrapped.
"It's moving along nicely," Mangold said, adding that he's optimistic about his chances to play against the Ravens. "Hopefully we'll be able to."
Mangold tried to lobby to play last week, but Ryan said the All-Pro center wasn't ready and cited the long flight to Oakland as one of the factors in the decision to leave him home.
"I think this week is better than last week, definitely," Mangold said. "Hopefully we don't need to convince them, and we can do it."
Cromartie bruised his ribs and a lung during the game against the Raiders and was examined at a hospital in the Oakland area. He appeared to move without discomfort during agility drills, but it's uncertain if he's ready for live action on the football field.
Cromartie wasn't in the locker room during media availability and is considered day to day, as is Mangold. He would be replaced in the starting lineup by Kyle Wilson if he's unavailable.
"I'd think if they practice, they are going to be very limited," Ryan said.
