Babin voided the final two years of his contract Monday, hitting the market before the Jaguars cut him.
Babin, who had 7 ½ sacks last season, was due to make $6 million in 2014 — more than the rebuilding team was willing to pay for a 33-year-old pass-rusher who's no longer in his prime.
Jacksonville could bring back Babin at a reduced rate if he doesn't find a suitor elsewhere.
The Jaguars already signed one defensive lineman, and Babin's departure could leave them in the market for another. Jacksonville signed former Seattle defensive end Red Bryant, a run-stopping end, to a four-year deal worth $17 million.
The Jags were tied for the fewest sacks (31) in the league last season.
