Both Ian Rapoport of NFL Network and Adam Schefter of ESPN report that Cooper (knee, ankle) is expected to play Sunday night against the Vikings.
That supports a previous report by Michael Gehlken of The Dallas Morning News that the "expectation remains that (Cooper will) start" Sunday's contest. Ideally, those who roster Cooper -- who is dealing with a bruised knee -- would have a contingency plan in place in case the unexpected occurs, but the signs point to him being a go for his team's 8:20 ET kickoff Sunday night.
