Carolina Panthers quarterback Cam Newton left Thursday's preseason game against the New England Patriots with a foot injury.
Per Max Henson of the team's official website, the Panthers star won't return.
The Athletic's Joe Person noted the injury appeared to occur when Danny Shelton wrapped up Newton's left ankle on a sack.
Newton's track record is one of the best among current NFL quarterbacks with a resume that includes the 2015 Most Valuable Player Award, three Pro Bowl selections and a first-team All-Pro nod. He also led the Panthers to Super Bowl 50 at the end of the 2015 season.
