What happened: The Minnesota Vikings are planning to start Carson Wentz at quarterback against the Buffalo Bills on Monday Night Football. Kyler Murray is dealing with a sore hamstring that would limit his mobility and risk further injury if he played. Wentz previously stepped into the starting lineup when Minnesota ruled out Murray earlier this season.

Why it matters: Minnesota seeks to protect Murray from compounding the soft-tissue injury as the second half of the schedule begins. The start gives Wentz an opportunity to direct Kevin O'Connell's offense against a 6-1 Buffalo team that represents one of the AFC's top contenders.

What to watch: Minnesota will evaluate Murray's mobility throughout the week before issuing an official game status designation. Kickoff between the Vikings and Bills is scheduled for Monday night.
