Johnson to Dolphins practice squad

The Dolphins have signed RB Duke Johnson to their practice squad. The 28-year-old spent a couple of weeks on Jacksonville's practice squad in September but has otherwise been unemployed since being released by the Texans in February. There's opportunity in after RB Malcolm Brown was placed on IR, but Johnson is only worth adding in the deepest of fantasy leagues right now. We'll see if he gets promoted to the active roster.
