The Jaguars and Lions settled the cases with the NFL Management Counsel and the NFL Players Association on Thursday.
An unspecified player filed a complaint about the Jaguars' practices. Lions union representative Jon Jansen says he didn't file a complaint and doesn't think a teammate would have done so without asking him.
"We will comply with the league's directive and we will continue to respect and emphasize the NFL's rules and regulations regarding the offseason training program," Lions general manager Martin Mayhew said in a statement.
Jacksonville canceled practices Monday and Tuesday, its final two on-the-field workouts before training camp.
"I don't think in any way this diminishes the amount of work we were able to get done; the energy and the effort was outstanding," Jaguars coach Jack Del Rio said Thursday. "I feel like we accomplished a great deal as a young football team that's very hungry, that's very eager, so I'm real proud of the effort our guys gave this spring."
The NFL's collective bargaining agreement sets rules for OTAs, which are noncontact drills without pads. Teams practice in shorts, shirts and helmets.
Oakland and Baltimore were penalized for similar infractions last week.
