Harper (concussion) was waived/injured by the Jaguars on Saturday, Mike Kaye of WTLV reports.
Harper suffered a concussion in the preseason finale and will likely revert to injured reserve if he clears waivers.
Harper is being evaluated for a concussion after going down while covering a punt in Thursday's matchup with the Falcons.
Harper had to be carted off the field with his head immobilized, Ryan O'Halloran of The Florida Times-Union reports. This is a scary sight for football fans, but the severity of the injury is unclear at this time.
