SAN DIEGO -- The San Diego Chargers have signed defensive tackle Alfonso Boone to help fill the void left when Jamal Williams was lost for the season with a triceps injury.
Boone spent the last two seasons with the AFC West rival Kansas City Chiefs. He was released in the final roster cutdown.
Williams, noted for his run-stuffing prowess, was hurt in the opener against Oakland and was put on injured reserve on Saturday.
