The San Francisco 49ers' top two offensive players have been sidelined since a 20-3 drubbing against the Seattle Seahawks on Oct. 22.

With a rematch looming in Seattle on Sunday, 49ers running back Carlos Hyde and wide receiver Anquan Boldin, along with cornerback Tramaine Brock, appear not much closer to returning to the lineup.

"None of those guys have gone full speed," San Francisco coach Jim Tomsula told reporters Monday. "Nobody's done anything at a full-tilt, yet. So we'll see where that is."

Hyde is dealing with a stress fracture in his foot sustained in a 30-27 loss at the New York Giants on Oct. 11. He was limited to 95 yards on 32 carries in the next two games before sitting out the final two contests prior to last weekend's bye.

"We're going to see where it's at, and see where it's going," Tomsula said. "He's obviously been doing things for conditioning. He's not running a ton. We'll see where he's at this week."

After backups Reggie Bush and Mike Davis sustained injuries that required surgery, the 49ers promoted running back Kendall Gaskins from the practice squad and signed free agents Shaun Draughn and Pierre Thomas. Thomas was subsequently released and replaced by Travaris Cadet.

Boldin had back together back-to-back 100-yard games before he was held to three catches for 39 yards by the Seahawks. Despite missing two games, the veteran wideout still has 13 more catches than anyone on the team.
