The Jaguars have released cornerback Aaron Ross today. Earlier Friday, they released safety Dawan Landry. Ross,30, signed a three-year, $9.75 million contract before last year. He started nine of 14 games, making 65 tackles but no interceptions. Ross joins Rashean Mathis and possibly Derek Cox as Jaguars cornerbacks who won’t be back this year. David Sullivan, the agent for Cox, said in an email today he and the Jaguars have exchanged contract numbers but he expects Cox to hit the open market at midnight as well as the signing period on Tuesday. The Jaguars have only two cornerbacks under contract for 2013 -- Mike Harris and Kevin Rutland. Although the move was likely based on performance and not money, Ross’ release does create salary cap space. He was due a $4.04 cap number this year, but now will have only $666,667 of “dead money” on the cap, creating more than $3 million of additional room. That puts the Jaguars nearly $30 million under the cap. Ross came to the Jaguars after five years (two Super Bowl titles) and 10 interceptions with the New York Giants.
