The 49ers have placed running back Kendall Hunter, wide receivers Mario Manningham and Kyle Williams and linebacker Darius Fleming on the active-PUP list, the club said Saturday.
Also, the club said it has put running back Marcus Lattimore, defensive tackle Tank Carradine, defensive tackle Quinton Dial and offensive tackle Luke Marquardt on the active/non-football injury list.
With the exceptions of Hunter (Achilles), Dial (toe) and Marquardt (foot), the players listed are all on the mend from knee injuries. All eight players count against the 49ers’ roster limit of 90. They can remain on these lists until the 49ers make their final roster cuts, the club said.
