Lonnie Johnson suffered a setback with his broken fibula, but it won't cost him much time at which point the Raiders big plans for him can commence.

Lonnie Johnson Jr., who appeared locked into a training camp battle with Jamal Adams for a starting role with Las Vegas, collided with stud defensive end Maxx Crosby and broke his fibula on Saturday, according to ESPN. The injury will end Johnson’s season before it began.

Vegas signed Chinn to work as a starter and re-signed Isaiah Pola-Mao to do the same. Thomas Harper and Christopher Smith filled in for Johnson after the injury, per Bonsignore. Smith is a 2023 fifth-round pick, while Harper — a 2024 Chargers UDFA — joined the Raiders via waiver claim last August.

Though the Raiders could be tempted to move Adams back to safety following Johnson's injury, it would be a bad idea. Firstly, Adams is thriving at linebacker, and defensive coordinator Patrick Graham has been pleased with his acclimation. Secondly, the aging defender no longer possesses the athleticism required to play a coverage role at safety.
