Woods did not play last week because of personal reasons.
He did not inform the team that he would be out last week until about three hours before kickoff, sources told ESPN's Adam Schefter.
Woods missed more practice time this past week before returning to work Thursday and proclaiming that he planned to play Monday night.
Woods' personal issue could require his attention at any moment, and the Rams have said they support him now and moving forward, providing no further details.
