Seattle Seahawks cornerback Richard Sherman has admitted that he does not speak to former school coach and current San Francisco 49ers boss Jim Harbaugh.

Sherman said that he had nothing to say about Seattle's NFC rivals and that he was focusing only on his own team.

"I don't have a relationship with him," Sherman told NFL.com.

"I don't try to go any route with him. I don't deal with him; he is not my coach. So I deal with what is going on in Seattle and I keep it there."

Sherman has made 119 combined tackles in his two NFL seasons for the Seahawks so far.
