Cobb was one of two players released on Tuesday as the team got down to the league-mandated 75 players.
Cobb had a disappointing rookie season in 2015. He spent the first half of last season on injured reserve with a calf injury. During the second half of the year, he had limited success carrying the football. The Titans have a pretty deep backfield, trading for DeMarco Murray and drafting Heisman Trophy winner Derrick Henry. The team also has running backs Dexter McCluster, Antonio Andrews, Bishop Sankey and David Fluellen.
