Possible lineup changes
In addressing the media in London on Monday, 49ers head coach Mike Singletary said that lineup changes are forthcoming.
"I feel that this week will be a pivotal week for us," he said. "I'm excited to see how we respond on Sunday to some of the changes we'll make this week to try to get better."
He didn't specify, but here are some of the players Singletary could be considering:
-- Right guard Chilo Rachal. Dealing with knee and shoulder injuries, Rachal has struggled with pass protection and run blocking. Meanwhile, backup Adam Snyder has played well.
-- Nickel linebacker NaVorro Bowman. The rookie was called for illegal contact during the Panthers' game-tying touchdown drive in the fourth quarter, and he has missed tackles. Takeo Spikes made the game-clinching interception against the Raiders.
-- Wide receiver Josh Morgan. He missed a key block that led to a 6-yard loss by Anthony Dixon in the red zone against Carolina, and missed on two long passes for possible touchdowns against the Raiders. Diminishing Morgan's role could create opportunities for Ted Ginn Jr. and Dominique Zeigler.
-- Tackle Anthony Davis. The rookie has committed false starts and holding penalties. He also gave up the shoulder-crunching sack that knocked quarterback Alex Smith out of Sunday's game. The 49ers don't have a clear replacement here. The team hasn't been comfortable with Barry Sims at right tackle, though he played well at left tackle last year when he replaced an injured Joe Staley.
