The San Francisco 49ers are one of at least 18 teams showing some kind of interest in Canadian Football League cornerback Delvin Breaux. This report came courtesy of ESPN's Adam Caplan last week, but I wanted to make sure everyone saw it. Caplan reported the 49ers were one of 18 teams looking to bring Breaux in for a visit or workout. He is free to sign with an NFL team as soon as February 10. As previously discussed, the 49ers might also be interested in CFL wide receiver Duron Carter.

Breaux is 6'1, weighs 195 pounds and just wrapped up the second season of his CFL career. He has recorded 62 tackles, one sack, one interception, two fumbles, and a defensive touchdown. Bleeding Green Nation read that Breaux ran a 4.38 40. He ended up in the CFL due to a crazy injury eight years ago that resulted in a broken neck, and bone blocking an artery. Check out this feature story about his comeback from the injury. Former NFL scout, and current Montreal Alouettes college scouting director Russell Lande thinks he could be an NFL starter in 2015.

The 49ers cornerback depth chart could see some significant change between now and training camp. The depth chart is currently as follows:

Tramaine Brock

Dontae Johnson

Jimmie Ward (nickel)

Leon McFadden

Marcus Cromartie

Keith Reaser

Kenneth Acker

Cameron Fuller

Free agents: Chris Culliver, Perrish Cox, Chris Cook

I would not be surprised to see the 49ers extend one of Cox or Culliver, but I do not expect both to re-sign. And if they did not re-sign either, Brock and Johnson would probably be the leading candidates to start next season. Well, based on how the roster currently looks. It is too early to say anything with certainty because free agency and the draft could lead to changes fairly quickly.
