After suffering a knee injury in their latest preseason game, Cowboys wide receiver Jonathan Mingo is reportedly going to be sidelined for an extended period.

As the New England Patriots took the practice fields on Monday morning in preparation for their upcoming preseason finale, one prominent and highly-touted receiver was conspicuous by his absence. Pats’ rookie receiver Efton Chism III — one of New England’s most-exciting young offensive weapons — was among the players who did not participate in the session.
