SANTA CLARA -- The 49ers have shown interest in quarterback Seneca Wallace and are expected to visit with the veteran free agent, a source told CSNBayArea.com.
The 49ers' backup quarterback situation is unsettled with Colt McCoy, Scott Tolzien and rookie B.J. Daniels seeing an equal number of snaps during practices this week, coach Jim Harbaugh said. McCoy is scheduled to enter Sunday's exhibition game against the Minnesota Vikings behind starter Colin Kaepernick, Harbaugh said.
Wallace, 33, was cut this week by the New Orleans Saints. He has appeared in 62 games with 21 starts over seven NFL seasons. He did not play in 2012 after being cut by the Cleveland Browns in training camp.
