• Griffin, nose tackle Barry Cofield and defensive end Stephen Bowen were voted co-captains Wednesday. They join left tackle Trent Williams, linebacker London Fletcher and special teams stalwart Lorenzo Alexander, who began the season as co-captains. Shanahan customarily has his teams vote on additional captains at midseason after leaders have time to emerge.
• Strong safety Brandon Meriweather (sprained left knee) was limited in practice. “He’s looking good, a lot of enthusiasm out there,” Shanahan. “Just keep your fingers crossed that there’s no setback tomorrow.”
