Sigle (ankle) won't play in Monday's Week 6 matchup against Washington, Cam Inman of The San Jose Mercury News reports.
Sigle is dealing with a high-ankle sprain that he suffered Week 4 versus Denver. The second-year safety missed this past Sunday's win over Seattle and is now set to sit out a second straight game. In Sigle's absence, Malik Mustapha will likely draw another start.
