Defensive lineman Roy Lopez got stepped on in practice Monday and sat out Tuesday. He’ll be out a few days, per head coach Dan Campbell. Second-year running back Sione Vaki injured his hamstring Monday. Campbell said there’s no timetable for his return.
“We’re really high on him from an offensive standpoint, certainly special teams,” Campbell said of Vaki. “He really helped us in special teams and we feel like he could do that again. But offensively, just to see what we could do with him, see if we could expand his role.
“We feel like just athletically, size-wise, explosiveness, power, there’s versatility in what he could do. He might be able to play multiple roles, multiple positions, so this kind of sets us back. But he’ll be in there rehabbing with Fisch (Lions Director of Player Health and Performance Brett Fischer), getting it right, getting strength back in it and then we’ll start over again.”
