Mykel Williams Practice Window Opens For San Francisco

The San Francisco 49ers opened the practice window for second-year defensive lineman Mykel Williams, who started the season on the PUP list while recovering from a torn ACL sustained late in his rookie year. General manager John Lynch noted Williams looks excellent and expects him to return as soon as he is eligible in Week 5 against the Seattle Seahawks, instantly injecting a major boost into San Francisco's defensive line.
