The Chargers have agreed to terms with linebacker Stephen Cooper on a one-year contract. Cooper, 31, played the last eight seasons with the Chargers and started 11 of 12 games played last year. "We are happy Coop decided to return to the Chargers," general manager A.J. Smith said in a statement. "He wanted to explore the free agent market and weigh his options. He will bring his experience and more veteran leadership to our linebacker corps."
