Okada (hamstring) did not participate in Monday's practice, Corbin K. Smith of SI.com reports.
Okada sat out Sunday's practice as well, marking consecutive missed sessions due to the hamstring injury. It appears increasingly unlikely the 27-year-old will be able to suit up for Wednesday's Week 1 matchup against the Patriots, and it remains to be seen who'll slide into Okada's starting strong safety role if he's indeed sidelined.
