Chargers tight end Antonio Gates will test his right foot in two to three weeks. Gates, who visited foot specialist Dr. Robert Anderson in North Carolina this week because of some pain, was diagnosed with plantar fasciitis. "You see guys out here working hard and you want to be a part of it," Gates said. "But you got to take care of issues off the field; take care of my foot and make sure I stay healthy. Because ultimately September is when it really starts, and I'm looking forward to that."
