Adams (knee) has been ruled out for the rest of Thursday's game against the Cowboys, Paul Kuharsky of PaulKuharsky.com reports.
Adams suffered the injury on a touchdown reception for the Cowboys early in the fourth quarter. He was carted off the field and quickly ruled out, suggesting the potential for a serious injury. If Adams is sidelined beyond Thursday's game, it would be a big blow to Tennessee's secondary, as he has regularly played over 80 percent of defensive snaps at free safety.
