While Chargers coach Anthony Lynn said he won’t know Melvin Gordon‘s availability until at least Friday, the running back knows now. Gordon has no doubt he will play Sunday against Oakland. “I’m good,” Gordon said, via Eric Williams of ESPN. “I’ll be ready on Sunday.” Gordon sprained his left ankle late in Sunday’s 14-7 victory over the Jets. He did not practice Wednesday. “He’s day-to-day,” Lynn said. “If it’s something he can play with, then he’ll play. But right now we won’t know until the end of the week.” The Chargers have listed Gordon as questionable four times this season due to knee, shoulder and foot injuries. He started all four games.
