Dolphins activate Arian Foster

Jameson Williams worked out twice a day with a personal trainer in Detroit, and he said he caught passes on the JUGS machine at his house.

“I did a lot of catching,” Williams said Tuesday, via video from Ben Raven of MLive. “I was doing like a hundred a day. It was every day. You can do the math on that. It was a lot of catches.”

Williams said his hamstring is healed up, and he’s “ready to go.”

Williams is expected to have a role this week, but the Lions likely have him on a pitch count as he works his way back into football shape, the story said. Outside of very deep leagues, it's probably best to wait-and-see on Williams this week, but is certainly worth a pickup and stash if he's still on your waiver wire.
