"As you go into the regular season, dependability in terms of knowing when a guy will be out there is important. We made a tough decision but one we felt like we had to."The other players released Saturday were receiver Steven Dunbar Jr.; tight ends Ross Dwelley and Cole Hikutini; defensive backs Antone Exum Jr., Dexter McCoil Cheap San Francisco 49ers Hoodie , Tarvarus McFadden, Emmanuel Moseley and Tyvis Powell; running backs Malcolm Johnson, Jeremy McNichols and Jeff Wilson Jr.; offensive linemen Andrew Lauderdale, Coleman Shelton and Najee Toran; quarterback Nick Mullens; defensive lineman Niles Scott; and linebacker Korey Toomer.The team also placed defensive lineman Kentavius Street on injured reserve and linebacker Reuben Foster and Victor Bolden Jr. on the suspended list.
