The Seattle Seahawks placed defensive tackle Jesse Williams on injured reserve Monday with a knee injury.
Williams, one of three fifth-round draft picks by Seattle, was unable to practice more than a few days in a row before having to take at least a day off throughout training camp. He played in the team's first two preseason games and started their opener against San Diego, but didn't record a tackle.
Seattle also terminated the contract of wide receiver Brett Swain and waived receiver Perez Ashford, linebackers Kyle Knox and Craig Wilkins, long-snapper Kyle Nelson, tight ends Jameson Konz and Andrei Lintz and defensive tackle Martin Parker.
Seattle still needs to make six additional moves to get under the league-mandated 75-man limit by Tuesday.
