San Francisco will start 35-year-old Randy Moss across from Michael Crabtreeon Sunday against the Arizona Cardinals. With rookie A.J. Jenkins and returner Ted Ginn the last men standing behind that duo, the return of Davis isn't a luxury for the 49ers. The team is thin at wideout, but Harbaugh confirmed he's not looking to add Terrell Owens or a veteran wideout.
"A.J. (Jenkins) will step up," Harbaugh said. "We'll look at a couple of other options at receiver, but that group will have to step up."
