PHILADELPHIA (973espn.com) - Could the Eagles add yet another cornerback to the mix before the regular season?

According to CBS Sports' Jason La Canfora, Philadelphia is one of six teams considering signing former Cleveland Browns Pro Bowl cornerback Joe Haden, who was released Wednesday morning.

La Canfora also lists Pittsburgh, Miami, New Orleans, San Francisco and Kansas City as teams discussing one-year, prove-it deals with the 28-year- old former top-10 pick.

A separate NFL source pegged the Steelers, Saints and Dallas Cowboys as likely options to 973espn.com with Pittsburgh as the leader in the clubhouse.

The Eagles have already traded for starting left cornerback Ronald Darby as well as potential slot option Dexter McDougle this summer. Currently, Jalen Mills is slotted to start opposite Darby with Patrick Robinson and McDougle battling for the slot position.

The team also has rookies Sidney Jones, who will likely begin the season on the NFI list as he continues to rehab from a torn Achilles, and Rasul Douglas for down the road.

After releasing veteran cornerback Ron Brooks on Wednesday, the Eagles have just over $13 million in cap space to work with so there is room to add Haden, who had battled injuries in recent seasons and was graded as the 88th best cornerback in the NFL by ProFootballFocus.com last season, a precipitous fall from consecutive Pro Bowl berths in 2013 and 2014.
