Mayfield has high-ankle sprain

Panthers QB Baker Mayfield suffered a high-ankle sprain in Sunday's loss to the 49ers, per NFL Network's Ian Rapoport. "That means he’ll miss time, but how much will be determined by more tests and opinions," Rapoport adds. With QB Sam Darnold still out with his own ankle injury, Carolina will turn to QB P.J. Walker. The 27-year-old owns a 57% completion rate and 6.2 yards-per-attempt average on 128 NFL passes. So, as bad as Mayfield has been, don't expect Walker to be an upgrade.
