The Denver Broncos signed wide receiver Greg Hardin, safety Charles Mitchell and linebacker Chase Vaughn, the team announced Monday.
The signings bring the Broncos’ roster to the offseason limit of 90.
Denver also waived punter Steven Clark and defensive tackle Mister Cobble in addition to designating defensive end John Youboty (Achilles tendon) as waived/injured.
Hardin is a rookie free agent out of North Dakota who started 39 of 42 games. He had 221 receptions for 3,583 yards with 32 touchdowns.
Mitchell is a second-year player who was waived by the Broncos last week before being brought back on a tryout basis during the team’s rookie mini-camp. He was a sixth-round draft choice of the Atlanta Falcons in 2012 out of Mississippi State.
Vaughn, an NFL rookie, has previous experience playing in the Arena Football League for the Spokane Shock in 2013, the United Football League with the Las Vegas Locomotives from 2010-12, the Canadian Football League’s Calgary Stampeders in 2012 and the Indoor Football League’s Colorado Ice in 2011). Vaughn played collegiately at Colorado State-Pueblo, where he was the school’s all-time sacks leader with 15.5.
