The offensive line shuffle continues at Rams Park.
Center Scott Wells (fractured fibula) and left tackle Jake Long (concussion) did not practice, but right guard Harvey Dahl, out since Oct. 28 since suffering a knee injury against Seattle, was a full participant in Wednesday's practice at Rams Park in Earth City.
Tim Barnes (Missouri) takes over at center for Wells. If Long can't go, Rodger Saffold will fill in.
Linebacker Daren Bates (concussion) and cornerback Brandon McGee (foot) were the other Rams who sat out practice. Both are key performers on special teams.
Defensive end Eugene Sims (neck) was limited in the Wednesday workout.
Due to a clerical error, a sack recorded by William Hayes on Sunday in the 23-13 loss to the 49ers in San Francisco was awarded to Robert Quinn.
On the play, Hayes ran down Colin Kaepernick and tackled him near the sideline. It was Hayes' fourth sack of the season.
With 13 sacks, Quinn is second in the NFL, trailing only the Colts' Robert Mathis, who has 15 ½.
