The Carolina Panthers won't make what coach Matt Rhule called a "major decision" on any position, particularly between quarterbacks Baker Mayfield and Sam Darnold, until after the Aug. 19 preseason game at New England.

Even then, Rhule might not make a decision if one hasn't clearly separated from the other after two joint practices in Foxborough, Massachusetts, and the game.

 "I'm not putting a timetable on the quarterback position until after we get back from the Patriots week," Rhule said after Saturday's scrimmage in which neither quarterback had a decisive advantage. "The Patriots week is a true litmus test for us. That will really show us where guys are."
