Kyle Shanahan said newcomer Laken Tomlinson has a chance to win a starting job at one of the 49ers' guard spots, perhaps left guard where incumbent Zane Beadles struggled Sunday against the Panthers.
"We'll look at that every week," Shanahan said. "We did last week, too. We've got a group of guys on our roster -- they'll battle. They had three days to do it last week; they'll have three days to battle and we'll put out (on) Sunday whatever we think our best lineup is."
Tomlinson, whom the 49ers acquired in a trade with the Detroit Lions on Aug.
