Pittsburgh saved $3.65 million by cutting ties with Gildon, who turns 32 next month and is the Steelers' career leader with 77 sacks.
Meanwhile, the Ravens plan on using Pro Bowl outside linebacker Peter Boulware as a situational pass rusher once he recovers from knee surgery. Boulware is expected to miss training camp, or at least the majority of August practice sessions.
Nolan said the team may consider adding another cornerback at some point.
The Ravens will open a mandatory full-team minicamp Monday that's expected to be attended by almost all veteran players, including running back Jamal Lewis.
Lewis has been indicted on federal drug conspiracy charges in Atlanta. Along with co-defendant Angelo Jackson, Lewis has pleaded not guilty and no trial date has been set.
Chris McAlister, the team's franchise player, is not expected to be there in an excused absence. Because the Pro Bowl cornerback hasn't signed his one-year tender of $7.1 million, he's not required to attend since he's technically not under contract.
