SANTA CLARA -– Running back Carlos Hyde, the NFL’s seventh-leading rusher, did not participate in 49ers practice Wednesday due to a foot injury.

Coach Jim Tomsula did not list Hyde as a player who would not practice when he met with the media earlier in the day. But Hyde was one of six players who did not practice, as the 49ers began their on-field preparations to face the Baltimore Ravens on Sunday at Levi’s Stadium.

Hyde has been one of the few bright spots for the 49ers (1-4) this season. He rushed for 375 yards (4.5 average) and three touchdowns in the 49ers' first five games.

Reggie Bush (calf) also did not practice, leaving rookies Jarryd Hayne and Mike Davis as the only running backs on the 49ers’ 53-man roster who were available. Bush did not play in the second half of the 49ers’ game Sunday against the New York Giants due to the tightness in his calf.

Tight end Vernon Davis took part in limited practice as he continues to nurse a knee bruise.

Davis took part in limited practice for three days last week before the 49ers took the unique step on Friday of ruling him out for the game. He did not travel with his teammates to New Jersey for the game.

When asked if Davis sustained a setback last week, Tomsula said, “He just wasn’t there.”

Tomsula said Davis showed no explosion when he was running, and Tomsula said he wanted Davis to continue to rehab and not take the chance of it becoming a lingering issue.

“So we were able to get three good days of treatment and working out there,” Tomsula said. “He did do some exploding on Sunday, not full tilt, but felt good there. . . We’re going to keep an eye on it, just to make sure. But I think well ahead of that one, so feeling good there.”

Outside linebacker Ahmad Brooks plans to play in Sunday's game after attending his sister's funeral on Wednesday, his agent told CSNBayArea.com.
