49ers RG Chilo Rachal was benched in favor of Adam Snyder during Sunday's win over the Bengals. Rachal committed three penalties and gave up two sacks in the first half. He only played in "heavy" packages in the second half. Coach Jim Harbaugh confirmed the job is now up for grabs. "To be determined," Harbaugh said about his starting right guard. "There's a competition there." Frank Gore should want Rachal in there as the better run blocker.
