Hopkins (ribs) and Fuller (calf/oblique) were the only two offensive players on the injury report listed as limited participants in practice.
Also limited was linebacker Zach Cunningham (knee), and cornerbacks Johnathan Joseph and Bradley Roby. Both corners are dealing with hamstring injuries -- Joseph's kept him out of Sunday's game against the Kansas City Chiefs and Roby went down in the third quarter.
Safety Tashaun Gipson (hip/wrist), wide receiver Kenny Stills (hamstring) and running backs Carlos Hyde (calf) and Taiwan Jones (hip) were all full participants in practice.
Stills has been out since the Week 4 loss to the Carolina Panthers.
Offensive linemen Tytus Howard (knee) and Greg Mancz (concussion) did not participate in practice Wednesday.
Howard left Sunday's game with a partially torn MCL and Mancz has not played since suffering a concussion against the Panthers.
