Panthers WR Kelvin Benjamin went down with what appeared to be a knee injury in practice today, and this is scary as hell for Carolina: the second-year receiver led the team in targets last year, and the Panthers are desperate to provide Cam Newton with options.

Benjamin appeared to twist his left leg during a 1 on 1 drill while trying to make a cut, and went down without contact, which is always ominous. He immediately grabbed his knee, and was taken from the field on the cart.
