The Ravens made several roster moves Tuesday including the releases of quarterback Keith Wenning and tight end Phillip Supernaw.A 2014 sixth-round pick, Wenning spent his entire rookie season on the Baltimore practice squad and was once viewed as a potential long-term backup for starter Joe Flacco. However, the free-agent acquisition of veteran Matt Schaub made it clear that the Ravens didn’t think much of Wenning’s future with the organization.The Ravens will also give spring and summer reps to former North Carolina quarterback Bryn Renner and rookie Jerry Lovelocke, an undrafted free agent from Prairie View A&M.Supernaw spent last season bouncing back and forth between the practice squad and the 53-man roster and even spent a brief time with the Kansas City Chiefs. In eight total games, he caught three passes for 30 yards.With the Ravens selecting tight ends Max Williams and Nick Boyle in this year’s draft to join 2014 third-round pick Crockett Gillmore, it was apparent that Supernaw was quite low on the depth chart. Veteran Dennis Pitta still hopes to play again this season, but his status remains in doubt despite a guaranteed 2015 salary.The Ravens signed Alabama guard Leon Brown, James Madison wide receiver Daniel Brown, and Rhode Island inside linebacker Andrew Bose. In addition to Wenning and Supernaw, rookie free agent outside linebacker Darius Allen was cut on Tuesday afternoon.
