Kalen King: Everything you need to know

The Panthers signed King to the active roster from their practice squad Saturday, Darin Gantt of the team's official site reports. King will now have an opportunity to make his NFL regular-season debut after joining the active roster. The 22-year-old should help bolster the team's depth in the secondary, as Jaycee Horn (concussion) and Corey Thornton (leg) are both dealing with injuries.

King (arm) is fully healthy and participated in training camp Sunday, Wes Hodkiewicz of Packers.com reports. King was seen with a cast on his right forearm during the Packers' minicamp in the early portion of the offseason. Before his injury, the first-year cornerback was turning heads after spending his rookie season on the practice squad. The 22-year-old is expected to work at nickel with the second-team defense now that he's back.

King (forearm) did not participate during minicamp Tuesday, Rob Demovsky of ESPN.com reports. King is evidently hurt enough that he needs to wear a cast on his right forearm, though it's not immediately clear what happened. Until he's ready to return to action, rookie seventh-rounder Micah Robinson could see higher leverage opportunities at practice.
