Though the Raiders could be tempted to move Adams back to safety following Johnson's injury, it would be a bad idea.

The Las Vegas Raiders suffered a significant injury during Sunday's training camp practice when safety Lonnie Johnson Jr. broke his fibula after colliding with teammate Maxx Crosby, according to ESPN.

Raiders safety Lonnie Johnson Jr. has suffered a broken fibula and will get an MRI to determine if there is additional damage, a source told ESPN.
